The Alarm Broadcast operator allows a slave to send several different types of event notifications to its master. The operator provides functionality for the following alarm types:
Diagnostic: A diagnostic alarm signals an event within a defined I/O module slot, for example over-temperature, short circuit, etc. From "Specification for PROFIBUS, Device Description and Device Integration, Volume 1: GSD" , Version 5.1 July 2008.
Process: A process alarm signals the occurrence of an event in the connected process, for instance upper limit value exceeded. 3
Pull: A pull alarm signals the withdrawal of a module at a defined I/O slot. 3
Plug: A plug alarm signals the insertion of a module at a defined I/O slot. From "Specification for PROFIBUS, Device Description and Device Integration, Volume 1: GSD" , Version 5.1 July 2008.
Status: A status alarm signals a change in the state of an I/O module, for instance run, stop or ready. 3
Update: An update alarm signals the change of a parameter in a defined I/O slot, for example, by a local operation or remote access. 3
A detailed overview of Design Pad operator functionality (including PROFIBUS operators) is described in publication PDG-TR-2011/13, the Design Pad Operators Reference.
