Transfer data from one PLC to another.
Transfer data from one PLC to another.
(OP)
I have two plc's that basically control one machine. One is a AB 5/04 and the other is a 5/01. What I would like to know is if it is possible to move the data, say an input or an output from one plc to the other without actually running a wire from the output of one to an input of the other. Would it be like transfering data to a panelview by using a block transfer or can it be done at all, I'm not real sure. I realize if it can be done, I would have to upgrade the 5/01 processor to a 5/04. This is not a problem though. I would appreciate any help on this and thanks in advance.

RE: Transfer data from one PLC to another.
Panelview may be on the same network.
But be aware about such handshaking speed.
On DH485 you may have up to ~0.5 sec delay reading signals from one PLC to another.

RE: Transfer data from one PLC to another.
The simplest method would be to use a 1747-PIC to interface from the 5/04 RS232 port to the 5/01 DH485 port.
The 5/04 RS232 port should be configured to DH485 protocol to say address 1. The 5/01 set to address 2.
The message instruction is simmple to use. Read the help.
