GENERAL PROCEDURE FOR CONNECTING USING GENERIC ETHERNET MODULE
All assembly pairs can be connected to a single ERSC using the same procedure within RSLogix 5000 environment:
1. Create a New Module in your Ethernet Tree
2. Select Generic Ethernet Module from the list of devices
3. Enter name and I.P. Address
4. Select the correct Comm Data type
5. Enter Input Assembly Instance Value and Size
6. Enter Output Assembly Instance Value and Size
7. Enter desired RPI value
For example, if you need to attach to 5 Ai2 modules that are in ZPA Mode, each module will have to have a unique
name and I.P. address (step 3) and steps 4, 5, 6, and 7 will use the same values for each ERSC.
EXAMPLE FOR AI2 MODULE IN ZPA MODE
This section will provide the set-by-step procedure for creating an instance of an Ai2 module into the I/O
configuration for an Allen-Bradley CompactLogix processor in RSLogix 5000 software.
Step #1
Add a New Module to the processor’s I/O
configuration by highlighting the processor’s
local Ethernet port in the I/O configuration
tree.
Right-clicking will show the context menu.
Select “New Module…”
