Re: S7 driver, how to change PDU size?
Hello,
I had a look at the options for the S7-driver, I could not find an option to change the PDU size.
Normally there is no need to change the PDU size.
Why do you want to modify it?

Hi Leopold,
I was trying to get WinCC OA to communicate with the Siemens PLCSIM. It seems to have a different protocol than a regular PLC so we used a software tool called Net2PLCSim for that and had to modify it to get the PDU size under the limit.
Anyway, pity WinCC OA does not support Siemens PLCSIM
