To make a long story short I am in the process of upgrading a PLC5/40C to a 1756-L81ES. I will be installing a 1756-CNB module. This processor talks to 3 different PLC’s. They are the following
Node 1 PLC5/40C
Node 20 PLC5/40C
Node 48 1756-CNB to 1756-L81 PLC slot 0.
Node 30 1756-L81ES (Upgrading from PLC5/40C)
I am going to be using rsnetworx to reschedule the network. In the I/O tree in studio I have node 1,20 setup for controller PLC5. I tell it what node it is exc. For node 48 I set it up as a CNB module and inserted the control Logix controller as slot 0. My question is if I want to send data let’s say N74:0 from Node 30 to N73:0 in node 1 for a length of 8 Bits where can I configure that? In rsnetworx I can send and receive data from on plc5 to another easily under the scan list configuration tool but if I select Node 30 in slot 0 and right click there is no option. I had to delete the old plc5 that I’m upgrading from the ControlNet configuration to merge my new processor into the schedule. I know this deleted all my connections from the old plc5 but I have a backup copy to look at. The question is how can I tell the new controller to take data from a tag and send it to INT files on the other plc5 through the ControlNet schedule. When I click node 1 in the I/o tree it just says what node it is exc and doesn’t give the option to correlate a tag that I want to send to another PLC and receive data exc.
