I have a PLC5 processor with both ControlNet and DH+. I am able to bridge DH+ to the PLC5 processor from a ControlLogix rack, but am having issues trying to bridge to it from another ControlLogix rack with ControlNet.
In the successful DH+ case, I have:
Rack 1:
Slot 12 – 1756-ENET/B
Slot 8 – 1756-DHRIO/B, DH+ Node 3
Rack 2:
PLC5, DH+ Node 10
I can use the PLC5 Driver with the ENET card IP Address along the with connection path 1, 8, 2 , 10 where:
1 - backplane
8 - DHRIO Slot Number in Rack1
2 - DH+ Channel of DHRIO Card
10 - DH+ address of Controller in Rack 2
In the unsuccessful ControlNet case, I have:
Rack 1:
Slot 9 – 1756-ENBT/A
Slot 2 – 1756-CNBR, ControlNet Node 17
Rack 2:
PLC5, ControlNet Node 4
I’m trying to use the PLC5 Driver with the ENBT IP Address along with Connection Path 1, 2, 2 , 4 where:
1 - backplane
2 – CNBR Slot Number in Rack1
2 – ControlNet Channel of CNBR Card
4 – ControlNet address of Controller in Rack 2
I can create a DDE/OPC topic in RSLinx using the ControlNet path and read data. I believe it comes up with the same path I’m using.
Do I have something wrong with the ControlNet connection path? Is this possible?
