6.5 PROFINET Diagnosis Alarms

The RX3i CEP reports its own non-fatal errors and errors on modules in the remote node using PROFINET
Pull/Plug or PROFINET Diagnosis alarms.
Diagnosis Alarms indicate any fault conditions other than a module add, loss, or mismatch that an RX3i CEP
Carrier needs to communicate to the PROFINET Controller. Most faults generate Diagnosis alarms.
When the RX3i CEP Carrier detects a fault condition, it sends a Diagnosis alarm to the I/O Controller. If there is
a Primary Application Relationship (AR) currently active that includes the affected module, the RX3i CEP sends
the Diagnosis alarm over that AR. Otherwise, the alarm is placed in diagnosis memory in the RX3i CEP Carrier
to be read later, and no alarm is sent. The RX3i CEP Carrier's OK LED is Amber ON and the FAULT status bit is
set to 1. An alarm is not generated on subsequent connections.
The RX3i CEP automatically clears (and sends Diagnosis Disappears alarms for) these diagnosis faults after the
fault condition has been corrected. If no additional conditions exist in memory, the OK LED is turned Green ON
and the FAULT status bit is set to 0.
The following table lists the faults reported to the I/O Controller. The RX3i CEP generates all of its application
faults as channel diagnosis faults. The AlarmType is Diagnosis or Diagnosis Disappears. The left column lists
the Channel Error Type in PROFINET.
Pull/Plug alarm is included in the Section 6.1,
