MEDISS is a Windows software that allows you to design control programs in instruction list mode for Simatic S5 and S7-200 PLCs based on GRAFCET. It is made up of three components:

Editing Module
Based on Grafcet guideline, you build the functional diagram of the automatism including the necessary actions and transitions. Then the sequential equations and the control program for Simatic S5 or Simatic S7-200 PLC are automatically generated.

COMGRAF Module
Any control programm written in a text file by Mediss or any other editor, can be transferred to the PLC in a structured way. Syntax errors are detected and user is advised of them.

VISGRAF Module
This is a supervision module for the PLC control program from a Grafcet point of view. You can see how the Grafcet states evolve in direct connection with the PLC via the PC's serial port. You can also inspect values of inputs, outputs, counters, timers, etc.
