protection relay 2

– During one phase PT failure, will overflux relay work? Has anyone seen this kind of voltage transformer connection?
– Why b phase winding is grounded on the secondary side?
– Can u share nameplate details of the PT
– yes, in an oil company, usually they only use 2 PT input and make it as delta connection in relay
20digsi 4, 11:51 – abb pcm600: That’s an open delta voltage transformer (or potential transformer)
20digsi 4, 11:52 – abb pcm600: It’s mainly used as an input to detect earth faults using neutral voltage displacement ..
20digsi 4, 11:54 – abb pcm600: Typically the sum of the voltage across D7 and D9 is zero ….however should there be an earth fault and one of the phases hit the ground … you will get voltage across the open point ….
20digsi 4, 11:55 – abb pcm600: Such schemes are used in ungrounded systems or on generator – transformer sets …. there is no path for earth fault …
20digsi 4, 11:57 – abb pcm600: Sorry open wye … but the scheme is same …
20digsi 4, 13:04 – abb pcm600: Open delta connection , Yellow phase normally will ground.

But as per drawing seen some conflict..
Norammly 2 VT Winding we can seen..

Normally like this


20digsi 4, 13:05 – abb pcm600: This is star connection with y phase grounded. Not an open delta. I was reading on internet its some old practice followed in UK.
20digsi 4, 13:35 – abb pcm600: Yeah … that’s an open Wye or Open Star … works the same way ..

26digsi 4, 05:04 – abb pcm600: That’s a very big open question …
26digsi 4, 05:07 – abb pcm600: Yes, it is really problematic to solve its protection system
26digsi 4, 05:16 – abb pcm600: Yes we typically run the neutrals to a common neutral bar. Install atleast 3 of neutral earthing resistor and and contactors
26digsi 4, 07:41 – abb pcm600: Are you talking about medium voltage generators
26digsi 4, 07:41 – abb pcm600: Yeah …

06etap, 11:56 – abb pcm600: Well, it can be a lot of stuff, but the first thing I always have for this alarm. SISTEM FAULT it means that you may have some unit programmed inside your PLC that is not connected in the field.
06etap, 11:56 – abb pcm600: So if it still works let it be
06etap, 11:56 -abb pcm600: with that alarm all parameters of slave address beocme red
06etap, 11:56 -abb pcm600: ok
06etap, 11:57 – abb pcm600: Is not something to concern, just be sure you have a good backup of the PLC program.
06etap, 11:58 -abb pcm600: but if it remains,it will not let startup of Engine
06etap, 12:09 – abb pcm600: Yes, but if it is already working, maybe is only a module programmed in the PLC but not connected in the field, but I say, I saw processes going on Years with this SF and nothing ever happend.

This not Bad contact Rubbon the message is clear (Micom Booting) with Led Alarm lightning in red Fast…
It’s like PC booting
I think it’s microprocessor …issue
07etap, 22:51 – abb pcm600: We have faced the same problem in our reliance industries jamnagar plant and Alstom it self give us solution and change all the ribbons. Micom rebooting issue may be from the HMI problem / relay power card problem but if it comes even after replacing HMI look forward with manufacturers.
It’s not just like pc booting issues. Their is no any chance of error in relay or bugs like microprocessor.

14etap, 15:49 – abb pcm600: Hello to all
What is the standard setting of the characteristic angle for directional overcurrent phase and ground (67/67N)?
14etap, 15:54 – abb pcm600: For typical distribution networks (upto 33 kV), I set it to 30 degrees. For sub transmission/transmission, I set it to 45 degrees, between the current phase and voltage polarizing quantity.
14etap, 15:55 – abb pcm600: However different scenarios may require different angles … and have to be worked out.
14etap, 15:58 – abb pcm600: This angle for directional phase overcurrent? What about the angle for directional ground overcurrent 67N?
14etap, 15:59 – abb pcm600: Are there any refferences for how to Make the setting for directional phase and ground overcurrent 67/67N?
14etap, 16:00 – abb pcm600: I would typically read the relay manual …
14etap, 16:00 – abb pcm600: And use the default recommended value
14etap, 16:01 – abb pcm600: The actual math behind setting them can be very tricky ..
14etap, 16:05 – abb pcm600: Which relay are you using ?
14etap, 16:09 – abb pcm600: Sepam s40
14etap, 16:10 – abb pcm600: The application is two parallel Transformers
14etap, 16:21 – abb pcm600: What’s the voltage level and how far is the relay from the supply transformer ?
14etap, 17:11 -abb pcm600“: From experience, RCA is 20~40
14etap, 17:42 – abb pcm600: For 67N, the value is dependent on the type of grounding.
Please refer to NPAG, it was clearly explained there
14etap, 17:45 – abb pcm600: Anyone have digsi4 Activation Key.?
14etap, 17:46 – abb pcm600: And for 67, if I am not mistaken, RCA is set based on impedance angle of the system

There is no Parameter menu in Functions? please clarify in details or send some snapshot
28etap, 12:15 – abb pcm600″: Hi Guys, I have a question
For 220KV level, which is suitable either CVT or IVT(PT)? And why
28etap, 12:16 – abb pcm600″: Usually we are adopting IVT(PT) in Andhra Pradesh India
28etap, 12:16 – abb pcm600: CVT always
28etap, 12:17 – abb pcm600″: Sir can you please support your statement… As we have observed the drift in secondary voltages are more in CVT compared to IVT over time span
28etap, 12:19 – abb pcm600: Mainly installation reasons …. they are lighter, cheaper
28etap, 12:20 – abb pcm600: Safer (transfer of emf when fault occurs)as there is no direct connection to the primary voltage source .
28etap, 12:20 – abb pcm600: Can you explain how does the voltage drift?
28etap, 12:22 – abb pcm600″: Deterioration in the capacitance levels over period of operations results in variations in secondary voltages
28etap, 12:29 – abb pcm600: Can’t that be fixed during maintenance? (Note: I don’t have any experience in maintenance and operation)
28etap, 12:31 – abb pcm600″: Even I don’t any experience in Maintenance. But I am not sure we can improve this in effective manner
28etap, 12:31 – abb pcm600: CVT for transmission circuits or High Voltage i.e greater than 66kV and IVT for distribution circuits 33kV and below
28etap, 12:33 – abb pcm600″: Moreover we are mostly using IVT in 220KV levels also so, I am not aware of fixing methods
28etap, 14:50 – abb pcm600: I believe it’s a cost trade off.
In India IVTs in 220kV class are more affordable than CVT. And yet you may see them actively used in 220kV stations where the transmission system is at 220kV level. This is because the same CVT would be used as coupling capacitor for PLCC communications as well.
28etap, 14:50 – abb pcm600: That’s my understanding
28etap, 18:04 – abb pcm600: This message was deleted
28etap, 18:05 – abb pcm600:
Hi guys,
Why when we calculate short circuit at transformer secondary we should consider no load ph to phase voltage not rated voltage?!

01etap, 23:37 -abb pcm600: Cheapest bro
02etap, 04:00 – abb pcm600: Another reason stones are used is ‘cause it helps in fire 🔥 mitigation, especially where oil traps/ sump pumps are not available.

The leaked oil will have less surface area exposed to air that can burn, there by reducing the fire hazard.

I have a problem in Micom P443 for Distance Protection. I have a problem in System Checks for Autoreclose,anyone can tell me what is the difference between CS1 Close Enable dan C/S AR Immediate ??
30etap, 12:35 -abb pcm600″: Cs1 close enable is the setting of sync check on which you want to recloser the cirxuit breaker like on Live Line Live Bus or Live bus Dead Line or Dead Line Dead Bus
30etap, 12:37 -abb pcm600″: If you enable c/s AR immediate then it means that if during the dead time system check conditions are met then it will reclose the breaker without waiting for the remaining dead time period,
30etap, 12:37 -abb pcm600″: Like for example if dead time is 1 sec
30etap, 12:38 -abb pcm600″: And system check conditions are met during 0.6 seconds of dead time ,then relay will give reclose command without waiting for the remaining 0.4seconds of dead time,
30etap, 12:39 -abb pcm600″: But you habe disables the system check conditions on shot1 that means it will reclose the breaker wothout looking into any system check conditions,
30etap, 12:39 -abb pcm600″: Sys check on shot 1 should be enabled too,

30etap, 19:01 – abb pcm600: Somebody help?
30etap, 20:56 – abb pcm600: It depends on the loading.. The higher its loading, more power needed to turn the output torque.. If you don’t have a load, just make sure your lower frequency setting has a minimal current to move the rotor..otherwise it will be overheat..

15etap 17:34 – abb pcm600: Note it’s RCBO not RCD
15etap 17:34 – abb pcm600: Yep🤦🏼‍♂️😅
15etap 17:34 – abb pcm600: Thanks alot
15etap 17:34 – abb pcm600: What s the difference?
15etap 17:35 – abb pcm600: Because some tell me it is the max number of trips
15etap 17:37 – abb pcm600: RCBO stands for residual current circuit breaker. It can open faults upto 6000A. It can be used for short circuit protection as well as sensitive faults of 30ma.

RCD is residual current device. It’s used only to pick up sensitive 30ma faults. They can’t open full short circuit currents.

Think of RCBO as RCD+MCB
15etap 17:37 – abb pcm600: No it’s the rated fault level ..

Is there any standard which speaks of about frequency of relay testing.
What is your experience…
Please share
25etap 21:20 -abb pcm600: Normally frequency of Numerical Relay testing depends on the utility practices.

In our utility we do annually. But in my opinion it is not required annually.
Numerical relay can be tested 5 years once.
Scheme testing can be done annually.

31etap, 20:14 – abb pcm600: ?!
31etap, 20:14 – abb pcm600: Yeah …
31etap, 20:14 – abb pcm600: Can i have it please 🙏
31etap, 20:15 – abb pcm600: Ok … I’ll send the pcm600 files tomorrow …
31etap, 20:15 – abb pcm600: Anything in particular you are after !’vv
31etap, 20:15 – abb pcm600: ??
31etap, 20:16 – abb pcm600: Current line differential relays are fairly straightforward..
31etap, 20:17 – abb pcm600: Is there a difference ?!
31etap, 20:43 – abb pcm600: Anyone knows what is the problem when a source (power plant) transmit power to a substation, then the neutral current monitored in power meter is a bit higher normally…
31etap, 20:46 – abb pcm600: I know that It means that there is an unbalance current on each phase. But what else can be that causes of phenomenon..
31etap, 20:49 – abb pcm600: The P.F on phase R and S is lagging 0.9, but the phase T shows a leading P.F
02etap 20:56 – abb pcm600:
Hello guys, i need some understanding on this problem..
02etap 20:57 – abb pcm600: In case it’s internal fault, just assume that the 87 T relay and Ref relay will trip…
02etap 20:58 -abb pcm600: your understanding is correct
02etap 20:59 – abb pcm600: But apart from it, if primary Overcurrent (50/51P) works, it will trip the CB 150 kV and how avout the CB 20 kV ??
02etap 21:00 – abb pcm600: Is it required to trip the CB 20 kV too ?
02etap 21:03 – abb pcm600: 87T trip, REF not really, depend on the fault. PP fault or 3P internal fault wont initiate REF
02etap 21:04 – abb pcm600: yep… to isolate the power from LV side too, in case bus section in 20 kV side is closed
02etap 21:05 – abb pcm600″: Depends on the control scheme we use…in most of the cases we adopt if HV side CB trips on protection LV CB also gets trip
02etap 21:08 – abb pcm600: REF is more sensitive for earth faults in the differential zone
02etap 21:08 – abb pcm600: If it is an earth fault REF trips faster than Diff.
02etap 21:12 – abb pcm600: Okayy..thank you everyone for the answer..
02etap 21:14 – abb pcm600: I think that 20 kV CB will need to trip too to prevent reverse power from remanent voltage (power) at Bus 20 kV side
02etap 21:15 – abb pcm600: But if there is a remanent voltage in 20 kV side, is it possible to induced voltage in primary winding to create a current..
02etap 21:16 – abb pcm600: Since you have NGR…earth fault close to neutral may nit be detected by REF
02etap 21:16 – abb pcm600: Percentage of unprotected zone can be calculated based on relay settings and CT ratio
02etap 21:31 – abb pcm600: Yes..due to the resistance, the sensitivity will be limited..
02etap 21:40 – abb pcm600: Have everyone ever tried, to induced voltage on secondary winding of step down Transformer i.e. lets say 150/33 kV. How about the primary winding transformer, does it will generate a low current or a harmonic current
02etap 23:29 -abb pcm600: Actually fault moves towards source. In actuall LV will not trip because fault current will move towards source side(150kv) side but if intertrip function is available then LV 20kv side will trip too
06etap 18:27 – abb pcm600:
06etap 18:29 – abb pcm600: Anyone knows about the calculation to get the value of Z1 Sensit. Iph>1 ? 🙏🙏
06etap 18:29 -abb pcm600″: Fault current should be above this value to identify zone 1 or zone 2 faults
06etap 18:30 – abb pcm600: 👌I got it.. But how to get this value ..
06etap 18:33 – abb pcm600: Okay. I have found it was 1.2 x CCC / CT Ratio
06etap 18:42 -abb pcm600″: Thanks

07etap 17:30 – abb pcm600: Since I close my CB thenthe IS time starts to count to set AR Block
07etap 17:32 -abb pcm600″: If cb is manually closed than after this time CB will be considered in service and Auto Recloser function will be enabled too,
07etap 17:33 – abb pcm600: Oh i see
07etap 17:33 – abb pcm600: But why it AR block indication is appeared.

05etap, 14:40 – abb pcm600:
when i turn on generator in this panel my generator has unstable frequency but when i operate it on manualy the frequecy stabilize. what may be the cause of this?
05etap, 14:40 – abb pcm600:
here is my genset set.
05etap, 14:43 – abb pcm600: Is ur gen set is synch with other gen
05etap, 14:43 – abb pcm600: no sir.
05etap, 14:59 – abb pcm600: What is voltage
05etap, 15:01 – abb pcm600: plzz check the gain & other setting for ur operator panel
05etap, 15:03 – abb pcm600: 460v
05etap, 15:03 – abb pcm600: there is no probel with engine & gen set itself it is the only problem with operator panel feed back signal which will be generate as per setting
05etap, 15:06 – abb pcm600:
05etap, 17:44 – abb pcm600: It is wierd
05etap, 17:44 – abb pcm600: Cause freq regulation is in generator itself not in woodward
05etap, 17:47 – abb pcm600: yes kind of.
05etap, 17:47 – abb pcm600: we try to bleed fuel on generator. but nothing happend
05etap, 18:17 – abb pcm600: I thought Woodward only do parallel synchronisation
05etap, 18:18 – abb pcm600: And some protection functiona
05etap, 18:19 – abb pcm600: but are only using small loads thats why we dont sync. our generators
05etap, 18:24 – abb pcm600: I looked at the manual for easygen
05etap, 18:24 – abb pcm600: Actually there is a function frequency control
05etap, 18:26 – abb pcm600: I have same system
05etap, 18:27 – abb pcm600: But never got time to check every function in Woodward
05etap, 18:28 – abb pcm600: i do check some function but the configuation has a password. the management told me that the supplier has the access to its unit .
05etap, 18:30 – abb pcm600: Please, contact the supplier

    12etap20:32 -abb pcm600″: There must b some issue ,
    12etap20:32 – abb pcm600: So this is not inrush
    12etap20:32 -abb pcm600″: Do TTR and winding resistance,
    12etap20:35 – abb pcm600: If it is the new commissioned plant then the issue will be in relay setting otherwise check transformer winding…do the IR…
    12etap20:35 – abb pcm600″: I did excitation test @ 10 kV and results was OK.
    12etap20:36 – abb pcm600″: Plant is in operation from last 4 years.
    12etap20:37 -abb pcm600″: You will have to do TTR and winding resistance to diagnose the matter ,

    29etap08:51 – oijoi: We have 50/1 5p15 CT installed on 33 kv feeder whos fault current initially was very less but now Power supplier has installed 50MVA transformer 11% impedance
    29etap08:55 – abb pcm600: And fault current is almost 8000Amps, I believe I need to upgrade protection CT in order to meet high fault current
    29etap08:55 – abb pcm600: Can anyone suggest
    29etap08:56 – abb pcm600: What’s the 33kv fault level ?
    29etap08:56 – abb pcm600: Now it is 8000 amps
    29etap08:56 – abb pcm600: Fault current level
    29etap08:58 – abb pcm600: 50 MVA transformer installed at state electricity board substation and we are consumers with 33 kv feeder voltage
    29etap09:00 – abb pcm600: 50MVA 220/33 KV star/ star connected transformer 11% impedance
    29etap09:01 – abb pcm600: Is the ct used only for over current and earth fault ?
    29etap09:01 – abb pcm600: Yes 50,51, 50G, 51G
    29etap09:04 – abb pcm600: Strictly speaking, I would put 200/1 5P40 2.5 VA
    29etap09:04 – abb pcm600: However if the relays have CT saturation detection, you could go lower.
    29etap09:04 – abb pcm600: What’s the relay being used ?
    29etap09:05 – abb pcm600:
    Micom P117
    29etap09:06 – abb pcm600: P127
    29etap09:07 – abb pcm600: Do you have the CT test results. In particular the DC resistance of the CT.
    29etap09:07 – abb pcm600: No sir
    29etap09:08 – abb pcm600: Can you give your consideration or calculations for this selection
    29etap09:08 – abb pcm600: 8000/200 =40.
    29etap09:09 – abb pcm600: So you need an accuracy limit factor of 40, with a low burden
  • https://elec-engg.com/wp-
  • 9etap09:09 – abb pcm600: You won’t need much burden as the relay is numerical and installed inside the switchgear
    29etap09:10 – abb pcm600: Got it Thanks
    29etap09:10 – abb pcm600: Noted
    29etap09:11 – abb pcm600: Your existing 50/1, 15 VA may actually work if you knew the DC resistance.
    29etap09:12 – abb pcm600: Do I have to check with CT testing kit??
    29etap09:12 – abb pcm600: I believe CT supplier should I have this information
    29etap09:13 – abb pcm600: Yeas if you have a test equipment (Omicron CR analyzer or similar) that should be easily possible
    29etap09:13 – abb pcm600: That’s possible, however normally the manufacturer will not specify the DC resistance for 5P/10P class act’s. No harm in asking them though
    29etap09:13 – abb pcm600: CT’s
    29etap09:14 – abb pcm600: CT Analyser
    29etap09:15 – abb pcm600: Ok I will check with him today, as I don’t have omicron kit available near by That the only option I have
    29etap09:15 – abb pcm600: How you coordinate DC resistance with fault current
    29etap09:20 – abb pcm600: Wait
    29etap09:20 – abb pcm600: I’ll write it down can’t type it it’s a bit of a process
    29etap09:21 – abb pcm600: Ok thanks
    29etap09:28 – abb pcm600:
    29etap09:29 – abb pcm600: So if Rct<= 1.75 ohm, you can use it 29etap09:30 – abb pcm600: For a 50/1 A ct this may be achievable. 29etap12:14 – abb pcm600:
    My suggestion will be , need to Replace 33 kv side CT with ,. 1000/1A, 5P10,15 VA
    29etap12:29 – abb pcm600: With this approach, I’ld reckoned checking the pick up values.

What is the difference of IN-HV Deriv Angle and IN-HV Measd Angle on monitoring online
08etap 11:46 -abb pcm600″: Derived means the neutral current have been calculated by summation of IA, IB and IC where as measured means neutral wire of ct secondary is connected to neutral element of the relay, and it is actually being measured,
08etap 11:50 – abb pcm600:
08etap 12:11 – abb pcm600: What is dead zone in protection??
08etap 12:13 -abb pcm600: Dead zone is Zone between CT & Open CB
08etap 12:14 – abb pcm600: It’s the point not seen in the zone of protection that of a relay. If a fault occurs at this point, the relay will not issue a trip. Usually between CT and breaker
08etap 13:48 – abb pcm600: Oabb pcm600 i see..IN HV deriv is neutral vector calculation, meanwhile In HV measd is a neutral REF winding
08etap 13:49 -abb pcm600″: We cannot say it is neutral ref winding until we see the setting of the relay,

DIGSI 4 video training sample:

DIGSI 4.93 is the user interface to configure SIPROTEC 4, SIPROTEC Compact and SIPROTEC 3 devices. It is designed with a modern, intuitive user interface. With DIGSI 4.93, from the numerous protection functions it is possible to easily select only those which are really required. The settings can be entered and displayed as primary or secondary values.

The DIGSI 4 matrix shows the user the complete configuration of the device at a glance. For example, the assignment of the LEDs, the binary inputs and the binary output relays are displayed in one image. With one click, the assignment can be changed.

You can assign passwords in order to protect your SIPROTEC devices against unintended changes to the device or unauthorized operations from the device. The default password of DIGSI 4 and DIGSI 5 as well as password management in SIPROTEC devices are discussed in this article. 

SIPROTEC 4 and DIGSI 4

SIPROTEC 4 passwords can only be changed by means of DIGSI 4. Proceed as follows in order to change an existing password. Select the password function and click on the Change command button. The Change Password dialog box is opened. Enter the old and the new password. An asterisk is displayed for each character you enter. As a confirmation enter the same sequence in the Confirm new password box. Confirm your entries by clicking on OK. Passwords are numbers with a length of up to 8 digits.

Access and change DIGSI 4 Passwords

The following access authorizations are preset at the factory in DIGSI 4:

  • Switching/tagging/updating (Password No. 1)
  • Unlocked switching (Password No. 2)
  • Test and diagnostics (Password No. 4)
  • Hardware test menus (Password No. 6)
  • Single parameters (Password No. 5)
  • Parameter set (Password No. 7)

Note: Password protection against unauthorized access is only active during on-line operation. The passwords for changing settings are not activated until the settings are downloaded to the device. They are irrelevant in the Offline mode. In order to de-activate a password, you have to know it!


At delivery, all passwords are set by default to 000000. The passwords for the Web Monitor are an exception: Here the default setting is 000002 for “Full Access”, 000001 for “Changes” and 000000 for “Read-only”.

If you have forgotten your password for changing a parameter set, a temporary password can be obtained from the SIEMENS hotline. This can be used to define a new user password for this function. Siemens hotline requires the registration number of your DIGSI 4 software package!

SIPROTEC 5 and DIGSI 5 Confirmation IDs and Connection Password

SIPROTEC 5 and DIGSI 5 Confirmation IDs and Connection Password

In SIPROTEC 5, there are no default passwords as in SIPROTEC 4. The Confirmation IDs in SIPROTEC 5 serves only as a safety measure. In terms of access control security, there’s the connection password feature as discussed in this article. Additionally, comprehensive role-based access control (RBAC) with central user management in SIPROTEC 5 firmware version V7.80 is introduced. With RBAC enabled, users can log in with their existing, centrally managed user IDs and passwords directly into the SIPROTEC 5 IED. The IED authenticates the user’s credentials using the RADIUS protocol and identifies his roles (authorization) from the central server. This RBAC feature is based on IEC62351-8, complementing it is the built-in Syslog support in SIPROTEC 5. The IEDs can also log all security-relevant user actions in a central log server, thereby also providing higher transparency and detection capabilities on IED operations.

Confirmation IDs are used for protection against unintentional and unauthorized operation. If a confirmation ID is activated, enter it before the relevant action is enabled by the SIPROTEC 5 device. For this purpose, the confirmation ID is transmitted encrypted to the SIPROTEC 5 device, where it is checked. A similar method is used for a communication connection between the DIGSI 5 and a SIPROTEC 5 device. To protect access to the SIPROTEC 5 device, there is a password for establishing the connection.
Confirmation IDs and the connection password can only be modified with DIGSI 5 but not with the SIPROTEC 5 device. You can also deactivate confirmation IDs and the connection password. However, Siemens recommends only using them for commissioning. During normal operation, confirmation IDs and the connection password are always activated.

DIGSI 5 Confirmation IDs

A confirmation ID consists of no more and no fewer than 6 digits, which you can freely select. For the following areas, you can assign different confirmation IDs:

  • Settings/operation: This confirmation ID controls access to parameter settings and process data. After installing DIGSI 5, the confirmation ID for this area has the default value 222222.
  • Switching (process): This confirmation ID controls access to the operational switching, in which the interlocking conditions are considered. After installing DIGSI 5, the confirmation ID for this area has the default value 333333.
  • Switching (unlocked):  This confirmation ID controls access to the non-interlocked switching, in which the interlocking conditions are ignored. Switching without interlocking can be a safety risk and requires precise knowledge of conditions in the substation. Before you can switch without interlocking with DIGSI 5, DIGSI 5 must-have switching authority. After installing DIGSI 5, the confirmation ID for this area has the default value 444444.
  • Switching authority:  This confirmation ID controls access for setting the switching authority. You can set the switching authority, such as on-site or remote operation, only with the key switch on the SIPROTEC 5 device. If the
  • confirmation ID for the switching authority is activated, this is queried by activating the key switch on the SIPROTEC 5 device. After installing DIGSI 5, the confirmation ID for this area has the default value 666666.

If a confirmation ID is deactivated, this is not queried before running the relevant action. This can result in unintended or unauthorized operating actions and even in material damage and personal injury!

DIGSI 5 Connection Password

A connection password ensures secure remote access to a SIPROTEC 5 device. The password must meet certain requirements. A password must be at least 8 characters long. It must include at least 1 upper-case letter, 1 lower-case letter, 1 digit, and 1 special character. No connection password is configured in a SIPROTEC 5 device when it is delivered.

If a password is activated, it must be entered correctly before DIGSI 5 can access the SIPROTEC 5 device. An activated connection password applies to all interfaces of the SIPROTEC 5 device. Access by plug & play is also protected with the password. Incorrect password entry is logged in the SIPROTEC 5 device. After 3 incorrect password entries, an alarm can be output via a binary output. The accessing DIGSI 5 is also blocked for further access for a few minutes.

If the connection password is deactivated, it will is not queried before a connection is established. This enables unauthorized persons to establish a connection between DIGSI 5 and a SIPROTEC 5 device.
