What can be forced in the S7-300? During simulation, it’s almost impossible to enforce constraints on point m, and as for the points in the DB block, assigning values to them is even more difficult
The input and output points can be forced, while the points in the M point and DB blocks can have values assigned to them. If a value has already been assigned to these points in the program, no further assignment is possible
In Siemens STEP7, only boolean values can be forced.
