Hello,
In the module Simatic 6ES7 331-7KF02-0AB0, there are connected four PT100 sensors.
All sensors show about 2 degrees too much (observed in the OP7 panel connected to the plc, and compared with the reference sensor).
I want to make temperature adjustments indicated on the panel op7, but I can not.
I only have to program the PLC, but I do not have a program to OP7.
OP7 probably read the temperatures directly from the peripheral inputs in the PLC (Piw304,...).
In the PLC program, analog inputs PIW are not transfered to a data block or markers word. In OP7 there are probably tags PIW304,....PIW316 for read data directly from analog inputs.
Is there any way to adjust the temperatures indicated on the OP7 ???
