Hello all,

I have been ask to convert a program from RSLogix500 to TIA V15.1 (S7-1500). The program uses a few PID loops. From RS500 the parameters of the PID blocks are known. Do parameters Kc, Ti, Td use the same units as in Siemens i.e. can I use the numbers for these parameters directly to the S7-1500 or I have to scale them.
Is the Loop update parameter in the SL500 the cyclic OB time for the S7-1500? I guess that in the SLC500 this time is seconds, correct?

Thank you.
