14.10 Monitoring Process Values (MONITOR_PV)

This module is designed for external monitoring of up to two process values, e.g. via the optional
4…20 mA output

. But also the relay outputs or the transistor outputs can be connected.

It is possible to use an input signal as a source for another (controller) module and loop the same
input signal through for external monitoring.

This module can also be used for logging process values only without any output connected.

MONITOR_PV

Each controller output signal is calculated depending on the configured input type.
If the input signal has a continuous input range (digital frequency input, analog inputs), the input range
will be represented linearly on the controller output. Please refer to the following table.
