PLC software
To create the PLC user program and to configure the PLC integrated in the MCI
Board, STEP 7, the standard tool for all SIMATIC S7 based automation systems is
used.
The STEP 7 software can run either, as usual, run on SIMATIC programming
devices PG 720, PG 740 or PG 760, or also directly on the PCU of the
SINUMERIK 840Di.
As the programming language, STEP 7 offers the following, tried and tested, non-
conforming PLC programming languages:
•
Statement list (STL)
•
Ladder diagram (LAD)
•
Control system flowchart (CSF)
