13 Alarms and Messages GLT x010
13.1 Message system
The messages and alarms to be reported by the controller are defined in the CODESYS application, and the
controller can also generate a number of internal alarms. The messages and alarms are transmitted from the
controller via the CAN bus to the system centre, which then stores, manages and, if necessary, forwards them.
A priority is assigned to each alarm/message. The priorities can be logically grouped using decades, which
enables maintenance group oriented alarm management.
13.2 Structure of the messages
Messages consist of date, time, the priority and message-specific plain text. They are shown on the display of
the operator terminal in 3 lines of 20 characters each. One line is used for the display of the active controller.
Line Example Data
1 Messages ID: xxxxx Active controller
2 Motor overload cut-out C1 Message text
3 20/05/17 10:20 IN Date (DD/MM/YY) and time of the message
4 20/05/17 10:25 OUT Date (DD/MM/YY) and time of clearance of the fault
Up to 100 alarm priorities are provided. The possible priorities for alarms and messages have now been
increased from the previous "---", 0, 1 and 2 to 99. This priority range is divided into 10 alarm groups (decades).
The 1 and 2 priorities (1,11,21,...91 and 2,12,22,...92) are reserved for high priority alarms that activate the
alarmrelays“PRIO1”and“PRIO2”aswellastheLEDs“PRIO1”and“PRIO2”onthefrontofthesystem
centre.
The highest priority number in each group (9,19,29,...99) is reserved for low priority alarms which should
only generate local alarm signalling (e.g. open cold room door).
All other priority numbers are intended for low priority alarms.
The lowest priority number in each group (0,10,20,..90) is reserved for messages that are only recorded in
the message list.

ONLY CI 3x00 with firmware version < 5.0.
The store computer versions do not support alarm priorities > 2 until version 5.0 and higher.
If priorities of 3..99 are configured in the controller, the store computer may have to be updated to
version 5.0 or higher via a firmware update. For more information about the store computer (e.g.
firmware and operating manual), see EDP.
