9.2 PROFINET Diagnostics
Alarms IMPACT67 sends diagnostic information in the form of alarms based on the
PROFINET specification V2.3.
NOTE
Diagnostics are signaled to the PLC in form of "incoming" or "outgoing"
alarms. If an alarm is present for only a short time, it is preferable if the PLC is
equipped with a diagnostic buffer. This diagnostic buffer saves alarm details
for later evaluation. If the PLC is not equipped with a diagnostic buffer, one
should be generated as application software.
