Although the RPI occurs continuously, the COS feature lets you to decide
whether changes in a module’s diagnostic detection should cause the module to
send real-time data to the owner-controller.
1. On the Module Properties dialog box, click the Configuration tab.
2. Do the following in the Enable Change of State column:
•
To enable the input module to send new data to the owner-controller at
the RPI, on input COS if it is enabled, and if a diagnostic fault occurs,
check the corresponding Off
→ On or On →Off checkbox for a point.
• To disable the feature, clear the corresponding checkbox for a point.
Real-time data is not sent when a diagnostic fault occurs but is still sent
at the specified RPI or on input COS if it is enabled.
3. Click OK.
