Also have a look at the following article, discussing adavantages and uses of the FDL protocol: http://support.automation.siemens.com/WW/view/en/26098555 Hope this helps, Daniel Chartier

Any suggestions about where to start and how to start, manual etc are most welcome. Cheers pals FDL is very easy to use for comms between PLC's another nice feature is that you can use the same software for an ethernet connection or a profibus connection You need to make a connection in NetPro You need to use the standard FC5 AG_SEND and FC6 AG_RECIEVEfrom the Simatic Net Library. example A M 0.7// Trigger pulse every second FP M 82.7// pos.edge = M 82.0 CALL FC 5 ACT :=M82.0 // send bit (in conjunction with dx3.0 ID :=2 // FDL connection number LADDR :=W#16#FFB // CP module adress SEND :=P#DB80.DBX20.0 BYTE 10 // DB,DW and lenght :db80 dw 20 length 10 byte LEN :=10 // length DONE :=M82.1 // if 1 then send ok ERROR :=M82.2 STATUS:=DB82.DBW2 CALL FC 6 ID :=2 // FDL connection number LADDR :=W#16#FFB // CP module adress RECV :=P#DB82.DBX20.0 BYTE 90 // DB,DW and lenght NDR :=M82.3 // if 1 then New Data Recieved ERROR :=M82.4 //Error flag STATUS:=DB82.DBW4 // Status code LEN :=DB82.DBW6 // received lenght Download this manual Bye Eric
