/ alarm options.

Process alarms
41767
Process alarms are used when a critical value or status occurs during the process in the plant. This
can be the case e.g. when the temperature of a tank is too low or too high.
The process alarms are application-specific. For this reason, the manufacturer does not implement
process alarms in this device.
