Hello all,
I am looking at a printout of a Bosch PC400 PLC. The printout is some hundred pages long, I am looking into upgrading to a new PLC as the program needs to be modified and I am unable to locate the software. The chap who programmed the PLC initially assigned all inputs and outputs to memory bits and used the bits througout the program. Is there any specific reason in doing this? I can only thing of one advantage: an output blows, to change the program to another one all you have to do is change one line in the program. Considering the PLC has 64 inputs and 50 outputs in use, quite some writing to do.
