Enhanced_Alarm_Mode:
If this bit is set to 1, the following alarm setpoints are frozen by the state on button actuation:
• Ports: LinkStatus.
• C-PLUG: Monitor C-PLUG.
• RED_Power: Monitor redundant power supply.
In this case, bits 0 and 1 must be ignored by the module.
For all connections (ports, C-PLUG. Red-Power) a deviation of the actual state from this
frozen state results in an alarm being generated. The response set with data record 200 is
ignored.
Note
This data record can also be read if the device is not in data transfer mode (PG access). It
supplies the current alarm setting for this port. This means that the current state can be
reread for diagnostics purposes. This is necessary because the alarm property can be
configured using the second parameterization option (button actuation). Bits 0,1, and 3 must
be set accordingly.
Data record 5:
Supplies the current alarm setting for this port
