Too high or too low device temperature
: The menu item Temperature serves to specify the lower
and upper temperature limits. If the temperature measured by the device reaches a value outside
of the defined limits, an alarm is triggered.
Failure of a supply voltage
: In the Voltage option, the monitoring of the input voltage(s) is defined.
Here you can specify which alarm is to be triggered if a voltage supply fails.
MRP protocol event
: With an active MRP ring redundancy, alarms can be triggered for detected
changes of the ring configuration.
Leakage current too high
: If a defined leakage current is exceeded here, an alarm can be
triggered.
Wrong neighbour
: By activating the point Wrong Neighbour, an alarm is triggered and also the
port assignment of the output configuration.
Exceeding the network utilisation at a port
: With the option Network Limit, messages can be
sent if the configured limit is exceeded.
SD card error
: If an error occurs in the SD card, a message is issued.
The created alarms can be linked to one or more alarm receivers which include:
SNMP Trap (in the SNMP menu, under Alarm, several trap receivers can be defined)
Relay contact
E-mail alarm (a receiver can be defined in the E-Mail Alarm menu)
If one of the specified alarms is detected and triggered, the software forwards the event to the
corresponding alarm receiver and documents this additionally as a log message.
Additionally, the alarms mentioned above can be stored in the hardware configuration of the controller. If a
trigger is activated, the switch issues an alarm message to the controller. This information can then be
processed further by programs in the PLC.
The respective alarm receiver can be defined in separate menus. Receivers for SNMP traps are defined in
the SNMP configuration menu (Advanced config
SNMP config). Receivers for e-mails can be defined in
the E-Mail Alarm menu (Network security
E-mail alarm)
