CM579-PNIO PROFINET IO Device Views¶
The different states for Node state and the entries for node data are the same data already described in CM579_PROFINET_CM_controller_list_slaves_views IO \ Controller List of Slaves View.
Alarm data
In PROFINET every device can have only 1 active alarm. The PROFINET IO Device diagnosis view displays the alarm data of the last active alarm of the selected device.
Note
The read out of these diagnostic data does NOT affect the alarm Function Blocks like it does in CANOPEN and PROFIBUS. Automation Builder reads only a local copy of the alarm data.
Time occurred
Date and time the alarm was triggered.
Time acknowledged
Date and time, the user has acknowledged the alarm via alarm Function Block.
There is no “alarm off” notification, but it is possible to get this information:
During the time the alarm condition is still active, the PROFINET IO Device repeats its alarm message to the Master continuously. So, if the alarm Function Block acknowledges an alarm, and shortly afterwards the alarm is again in not acknowledged state -> this means, the alarm cause is not gone. Otherwise it is gone.
If there is more than 1 alarm triggered on 1 Slave, it could happen that after the acknowledgement of 1 alarm the other alarm gets the active alarm. So the data displayed could switch between the different alarm causes.
Slot / SubSlot / ModuleID and SubModuleID are addressing information to locate the alarm cause/area on a PROFINET IO Device.
Alarm priority
There are 2 alarm priorities : ALARM_HIGH and ALARM_LOW

The additional alarm data are completely manufacturer specific data.
Every manufacturer can specify a User structure-ID which describes a structured data called Additional Alarmdata.
For ABB PROFINET IO Devices the structure is well known and the add. Alarm data can be displayed decoded into details and error codes.
