No-Reply alarm messages

  • Last UpdatedApr 24, 2025

If data is not received from the remote after a specified number of retries, the remote shifts to the "NO REPLY" state and the system logs an event. If the remote stays in this state for longer than the Administrator-configured timeout value, the system issues a "NO REPLY" alarm.

Note: This is the default behavior.

The alarm message takes the following format:

Communications on RemoteName - invalid message - no reply - unavailable for > TimeSinceProcessingOfLastGoodValue seconds
