Dialled Alarm Handling
When an alarm is triggered in the RTU, it will call the SCADA system in order to be polled
by the SCADA system for the alarm list. For the SCADA system to recognize which RTU that
is making the call, a caller id is sent to the SCADA system.
Structure: Caller id
The caller id is generated automatically by the RTU.
• Syntax: FLYGT_<protocol\>_<station number\>
• Example 1: If the protocol is Modbus and the station number is 31, the RTU generates
the Caller id: FLYGT_MODBUS_31
• Example 2: If the station number is changed from 31 to 32, the RTU generates a new
Caller id: FLYGT_MODBUS_32
Function: Alarm call
The table below shows an outgoing alarm call from the RTU to the SCADA system.
Phase RTU SCADA system
1 Alarm is generated.
2 Calls the SCADA system.
3 Sends its caller id. Caller id field in the SCADA system must correspond to the caller
id sent from the RTU.
4 If caller id is not supported by the SCADA system, it will request a
PLC_ID from the RTU.
5 Polls the RTU for active alarms.
6 Acknowledges the alarms.
