Hi,
I have a new project using Siemens ET200 distributed I/O, I have 40 channels of 4-20mA inputs in total.
I need to build in a calibration function for each one, at the moment I have a standard "Calibration" FB which I use in all my projects. I normally call an instance of the FB for each input from OB1 as I normally only have a couple of AI.
Is this the best way to do it for 40 channels of I/O? It just seems a bit cluttered to call the FB 40 times in OB1.
Would you put the call for each input in a separate FC and then call that from OB1?
Thanks,
