16.3 PROFINET Alarm Mechanism
16.3.1 General
PROFINET devices accomplish 99.9% of their communication via the cyclic, real-time
communications channel. Data is produced according to a pre-defined format, and it’s
sent on a schedule that doesn’t care if the data changes.
Alarms are really useful for the 0.1% of communication needs that can’t be handled in
that pre-defined cyclic format. They’re event-driven, so a PROFINET device will only send
them if an event happens that the PROFINET controller needs to know about.
16.3.2 PROFINET Alarm Structure
Alarms can encode data in two different ways, as either a Diagnostic Alarm or a Process
Alarm. We’re going to focus on Diagnostic Alarms in this section.
PROFINET defines diagnosis types of different detail to cover different use cases. The
type of a diagnosis is associated with a 16 bit unsigned integer called User Structure
Identifier. Here we consider diagnosis types with the USI 8000h (representing a Channel
Diagnosis).
A Channel Diagnosis is made of a single 16 Bit Error Code called Channel Error Type.
The Channel Error Type is characterizing the problem.
