Communication
In this chapter, you will establish communication between two PLC-5/40C
processors, bridging over two ControlNet networks. Change your existing
system to the following configuration.
1756-DHRIO Module
(in slot 2)
1756-CNB Module
(in slot 0)
ControlNet node 11
ControlNet Network #1
PLC-5/40C Processor
(ControlNet node 1)
In this example, you send a PLC-5 Typed Write message from the
PLC-5/40C processor at ControlNet node 1, network 1, to the PLC-5/40C
processor at ControlNet node 2, network 2.
Note that the multi-hop feature described in this chapter requires series
E/D.1 or F/A.1 processors and RSLogix5 software, version 3.2 or greater.
