12) Apply any changes to the settings using the “Set” button.
13) You should now be able to confirm that the 1756-ENBT/A module is

web browser.

ControlLogix Example: I/O Messaging
This section will demonstrate how to setup and use an EtherNet/IP I/O
connection via vendor-specific assembly instances 100 & 150. EtherNet/IP I/O
messaging allows the gateway’s addresses to be directly mapped into tags in the
ControlLogix PLC. Once an I/O connection is established, it is automatically
synchronized at an interval defined by the Requested Packet Interval (RPI).
1) Switch to offline mode.
2) Right click on the 1756-ENBT/A node under the I/O Configuration in the
controller organizer view and choose “New Module…”
3) Choose “Generic Ethernet Module” in the Select Module dialog box and click
“OK”. Refer to Figure 62.

4) The module properties dialog box will open (refer to Figure 63). Enter a
Name and Description which will allow easy identification of the gateway on
the network (the tags created in RSLogix 5000 will be derived from this
Name). Because the data type of the gateway’s database is entirely subject
to interpretation, an appropriate “Comm Format” must be chosen which
makes the transferred data meaningful to the application. For this specific
example, the “Comm Format” is set to “Data-SINT”. Enter the IP address of
the targeted gateway.
