Alarms handling
The following describes how to handle alarms in Regula Master TCP – the procedure and which commands to use. In the
webserver Pascal Operate the alarms for the configured controllers are listed in the Advanced section, which is reserved
for “service” login, but active alarms will be readable for user and operator login as well. Here is an example for a Local
RM:
Modbus/EXOline TCP
In the Lindab Pascal Signal list Modbus–Exoline there are alarm signal registers listed in both Discrete Inputs and in Input
registers. The alarm signals in the Discrete Inputs are showing actual values (0/1, second by second), which is only in-
tended for monitoring, e.g. error diagnostics. To see alarm/error status use Input register signals 2000-2178.
These alarms can have the following values: 1=Normal; 2=Blocked; 4=Cancelled; 5=Returned 7= Alarm
Commands for these alarms are found in Holding register signals 3000-3001. In Holding register 3000, set the alarm
number, where 1 = Input register 2000, 2 = Input register 2001, etc. (alarm number = Input register number – 1999). Alarm
numbers can also be seen in Pascal Operate Alarm status.
In Holding register 3001, the command for the selected alarm number is set. The possible commands are 1=Acknowl-
edge, 2=Block, 3=Unblock.
A Cancelled or Returned alarm will be set into Normal, after an Acknowledge command.
