Chapter 2 Manage event tasks
Make sure your module can trigger an event task
To use an input module to trigger an event task, the module must support event
task triggering. If the module is in a remote location, the associated
communication modules must also support event triggering.
The following table lists Rockwell Automation modules that have been tested for
event task triggering. Some third-party modules may also support event task
triggering. Before you use a third-party module, check with the supplier to validate
the operation of the module.

Checklist for an Input Event Task
Use the following checklist when creating an Input Event Task.
For This Make Sure You
1. Input module type For the fastest response, use these modules:
•
For fastest digital response, use a 1756-IB32/B module.
• For fastest analog response, use a 1756-IF4FXOF2F module.
2. I/O module location
Place the module that triggers the event and the modules that respond to the event (outputs) in the same chassis as the controller.
Remote modules add network communication to the response time.
3. Number of local modules Limit the number of modules in the local chassis.
Additional modules increase the potential for backplane delays.
