PID Control using FB41 for Siemens S7-300 PLC
Originally posted by Donald Tan on 20 December, 2002 - 11:19 am
I am an undergraduate student who is currently trying to program a Siemens S7-300 PLC (CPU 313) for PID control using FB 41. Where can I find more examples and more details on how to use FB41. There is none inside the Siemens PID control manual for the FB41. What are the important parameters that need to be configured?
