I/O Messaging Example
The following example illustrates how an AL5010 can be configured to
communicate with a ControlLogix processor using I/O messaging. Utilizing
this information along with the AL5010 Object definitions (on page B-19), it
should be possible to adapt these directions for other EtherNet/IP devices.
When EtherNet/IP is enabled on the AL5010, EtherNet/IP I/O Messaging is
automatically enabled. No further configuration is needed to setup I/O
messaging.
Since the ControlLogix processor will treat the AL5010 as an I/O device, to
setup an EtherNet/IP I/O message transfer between an AL5010 and a
ControlLogix processor, you need to configure your AL5010 as a Generic
Ethernet Module in the ControlLogix RSLogix 5000 interface I/O tree.
To add a module:
1. Under the I/O Configuration Tree, right-click on the entry for your
Ethernet module (e.g., 1756-ENET/A) and select New Module.
2. You will be presented with a list of options similar to what is shown
below. From this list select ETHERNET-MODULE for the Generic
Ethernet Module.
3. Specify the Module Properties for your AL5010.
a. The most important step is that you must first set the Comm
Format to Data-INT. This must be done first since it cannot be
changed later.
b. After this you can specify the Name, Description and IP
Address of the AL5010.
4. The Connection Parameters must be specified as follows:
