I have not used anything but these: in the right Panel "instructions".

Hi,

those libraries were not migrated to S7-1500.

But you can find the most important blocks in different places:

NONLIN, SPLT_RAN, ROC_LIM:
Instruction task card in programming editor -> Technology -> PID Control -> Auxiliary functions.
New instruction names are: Polyline, SplitRange, RampFunction

RMP_SOAK:
Can be found in application example "library of general functions" under following link:
https://support.industry.siemens.com/cs/ww/en/view/109479728
The block is called LGF_Ramp there.

LAG1ST, LAG2ND, DIF:
Can be found in application example "LSim Block library" under following link:
https://support.industry.siemens.com/cs/ww/en/view/79047707

Hi,

Don't try to use the Blocks PID of S7-300 / S7-400.  For S7-1500 you've, on TIA PORTAL, like  Foldesi says, the new blocks to control PID...

I do not know you examined this document;

I think this is the most detailed document for PID control in Strain Documents..
