Diagnostic Telegram for PROFIBUS DP
Overview
A Diagnostic Telegram is sent by the LTMR controller when:
-
There is a change of node address,
-
A system shut down (due to a power cycle, soft reboot, or watch dog) is detected,
-
A detected error or an alarm occurs.
The maximum length of a diagnostic telegram is 36 bytes. This information is useful for PROFIBUS DP primary (master) configuration.
