Has anyone ever setup communication between a Siemens S7300 to a ControlLogix PLC using a Prosoft MVI-PDPS slave module? The Siemens is the master and the Prosoft card is the slave.
I can see the Prosoft card on the profibus network, but when I try and read using SFC14 (DPRD_DAT), it gives me the following error:
"The length of the specified destination area is not identical to the user data length configured with STEP 7"
I have set up the prosoft card for 50 words of I/O. I have set up the module in Step7 with 50 words of i/O.
