Network Message Example 1:
MicroLogix 1400 Ethernet to SLC5/04 DH+ via ENET & DHRIO
The following illustrates the MicroLogix 1400 (CH1 Ethernet) sending a
remote message to a SLC5/04 processor (DH+ Node 51). The remote
message will s an ENET module, a ControlLogix chassis (Gateway) and a
DHRIO module. In order for the message to pass through the network, a
MultiHop MSG must be setup and a DHRIO Routing table must exist.
Belden 9463 "Blue Hose" cable is used to connect the DH+ devices on the
network. Ethernet cable and an Ethernet hub are used to connect the
ENET module and the MicroLogix 1400 CH1 Ethernet ports together.
