Hi,

technological instructions, such as "PID_Compact", "PID_3Step" and "PID_Temp", for the implementation of control tasks are supported by S7-1500R/H CPU starting with firmware version V2.8. Since this version requires STEP 7 TIA Portal V16 or newer, you can't use it in V15. So you need an upgrade to a newer version.

Note: In a few minutes, the SPS fair in Nuremberg will be opened. Siemens will show the V18 of TIA Portal there (if the plan was not canceled at short notice). The new version should be available at the end of November. In your place, I would switch to V17 using the trial version and buy the upgrade for V18 later.

Kind regards
Stefan
