Peer-to-Peer Messaging 5-3
To configure the route address (nodes 100 to 149), write a
485CIF/PLC2 message with 4 integer data words. An example is
shown in the next section of this chapter.
The procedure to send configuration data (nodes 100 to 149), or data
(nodes 0 to 49) is exactly the same as discussed previously in
‘Configuring ENI/ENIW Data Parameters’ on page 4-22.
Open the message instruction and enter the appropriate variables. The
variables are described in Table 5.3 on page 5-4.
IMPORTANT
In the ENI/ENIW, node addresses 45 through 49 are
dedicated for sending messages to any Logix
controllers with integral Ethernet ports. In addition,
when sending messages to a ControlLogix controller
via a 1756-ENBT, the controller MUST be in slot 0 of
the ControlLogix chassis for the message to be
delivered to it.
Node addresses 0 through 44 are to be used for all
other Ethernet devices, such as other MicroLogix
controllers connected to ENI/ENIW modules or other
controllers with integral Ethernet ports, such as SLC
5/05, PLC-5E, and MicroLogix 1100.
