12) Apply the settings using the “Set” button.

configured properly by (for example) opening the module’s web interface in

a web browser.

13.2.4 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 drive’s registers 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-ENET/B 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 66.

4) The module properties dialog box will open (refer to Figure 67). Enter a

Name and Description which will allow easy identification of the drive on

the network (the tags created in RSLogix 5000 will be derived from this

Name). Because all drive data is stored as 16-bit registers, change the

“Comm Format” selection to “Data-INT”. Enter the IP address of the

targeted interface card.
