I need to connect an S5-115U to a MP370 using a current loop connection (tty) using a S5 AS511 connection ?
I was wondering if I have to use any special FB's in the S5 plc program for proper communications ?
At the present time I am trying to figure out the easiest way to link a 115U-CPU943B PLC to an MP 370 and eventually to an S7 PLC. I could use a IM308C profibus module but at present there is a serial comm board in the last slot of the rack for an I/O extended. And I can't very well use the IM308C and the serial board at the same time without having to rebuild the PLC rack to a different configuration. Have any good ideas ?? Maybe the profibus is better than AS511...
