The programming instructions describe the use of standard function blocks FB34...FB37. They serve controlling S7 analog blocks in a ET 200M from a S5 PLC. Prerequisites of using these standard function blocks is setting parameters "Format of analog values to S5 format" of the ET 200M. The interface between S5-CPU and ET 200M is implemented via PROFIBUS-DP with the interface modules IM-308C in the PLC of the S5 and IM153-1 in the distributed periphery device ET 200M of S7.
