12 Alarms and Messages VS 3015 CT
12.1 Message System
A number of messages are recognised by the system and stored with date, time and the priority in the internal
log memory of the system.
Received / sent messages are stored in the log memory. The time resolution is one
minute. The messages are stored in the log memory in the chronological order of their generation. The log
memory has a capacity of 200 entries. If the log memory is filled, the latest message overwrites the oldest entry
(ring buffer).
12.2 Message Structure
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 Pos: xxxxx Active controller
2 Motor protection switch V1 Message text
3 20.5.98 10:20 ON Date and time of the message
4 20.5.98 10:25 OFF Clearance of the fault
Up to 100 alarm priorities are provided. Possible priorities for alarms and messages have now been raised 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 which activate
the alarm relays "PRIO1" and "PRIO2" as well as the LEDs "PRIO1" and "PRIO2" on the front of the store
computer.
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 designed for low priority alarms.
The lowest priority number in each group (0,10,20,..90) is reserved for messages which are only recorded in
the message list.
If the priority is set to "–", no message is generated.
This division into alarm groups (decades) facilitates maintenance group oriented alarm management.
For Version 2.0 and higher, an automatically generated message with the specified priority 0 (only archived in
the message list) is sent with the following text when any message priority is changed:
Prio M xxx:
p1 > p2
whereby xxx = message number
p1: old message priority
p2: new message priority
The log memory is buffered so that no messages are lost in the event of power failure. The messages
can be retrieved using the operator terminal. The latest message is output as the first one. The
contents of the log memory can be deleted using the operator terminal. Messages are also sent via the
CAN bus to display the current message using the operator terminal and thus the system centre can
establish a central fault message memory for the complete refrigeration pack system.

The alarm priorities --, 0..2 correspond to the remote alarm messaging concept of older store computer
versions with firmware versions <5.0. If priorities from 3..99 are configured in the controller then the
store computer must be updated to a firmware version of 5.0 or higher. Further information is provided
in the store computer operating instruction.
