Siemens LOGO!Soft Comfort – stands for sensationally easy and quick configuration. This allows the creation of user programs by selecting the respective functions and their connection via drag-and-drop. This applies to the function block diagram and ladder diagram.

It has been proven useful to program the switching program step-by-step and to simulate and test it on the PC offline. This approach prevents time-consuming troubleshooting in the entire program. short configuration times are accomplished by creating your own macro blocks in which frequently recurring program parts are stored in a macro library.

Creating the switching program:

    • Select functions and place them in the drawing area
    • Select the start and end point of the connection with the cursor and the software automatically “wires” the connection
    • The parameters of the functions, such as timers, threshold values, setpoints are defined in clearly structured dialog boxes
  • Simulation of the entire switching program with all functions now takes place on the PC while optimizing the parameters
  • Analog signals can be simulated with real values (e.g. temperature – 20 ºC to + 80 ºC)
  • Time-controlled as well as cyclic simulation can be used
  • Even time- and date-dependent switching functions can be simulated
  • Realistic representation of the LOGO! display within the simulation
  • Display of states for all functions, parameters and actual values
  • Do not forget to save the intermediate steps

Commissioning with LOGO!:

    • Wire the LOGO! as specified and connect to the PC with Ethernet cable
    • In the tested program, execute the function “Options / Transfer / PC to the LOGO!”
    • If several LOGO!s are connected, select the corresponding LOGO!
    • The software registers whether the PC has a matching IP address for the communication, then suggests an alternative IP address, sets it once it has been confirmed and then transfers the program to the LOGO!
  • Activate online test with display of states and actual values of LOGO! in RUN mode.


Professional documentation is often quite time-consuming and is therefore frequently neglected.
Gaps will arise after the commissioning phase, if not before. LOGO! Soft Comfort supports you in this endeavor and will print updated and standard-compliant documentation at the push of a button.

    • We recommend naming the inputs and outputs
    • Additional comments can be assigned to every function
    • Individual placement and formatting of free text in the documentation
    • Clearly structured switching program display across several pages can be set
    • Professional printout with all necessary project information and standard-compliant borders
    • Separate printout of parameters and I/O names is possible
  • Integration in standard Windows applications is possible by saving as .pdf, .gif or .jpg

System Requirements:

  • Microsoft Windows XP SP3, 7 SP1 or 10
  • Main processor 2 GHz or higher
  • 1 GB RAM or higher
  • 5 GB free hard disk space
