Hello,
Can someone help me with the connection between the CompactLogix L43 and SLC5/04 using DH485 network? I'm interested in how quickly I can share about 30 bytes of data between the PLC's using the MSG command in RS5000.

Hi there, the SLC504 you mentioned does not use DH485, it has RS232 DF1 or DH+. Can you just clarify the exact part numbers of both PLC systems you have...

Regards.

Ok. It looks exactly like this: CompactLogix 1768-L43 to the RS232 module is connected 1761-NET_AIC, then the connection is drawn DH485 and then the second module is a 1761-NET-AIC connected to Channel 0 (RS-232 DF1) of SLC5/04
Best regards
