Voltage and Current Monitoring
5.9.1 Description
The voltage and current module sends messages about
over-current, short-circuit, over-voltage and under-voltage.
Over-voltage and under-voltage detection starts a timer. If
the voltage level does not return to the normal operating
voltage threshold before the timer expires, the module
sends the messages.
The messages include device status, IO-Link events,
process data and LED signaling.
5.9.2 Mathematics/Algorithm
In SIO-operation, the threshold for under-voltage is 10 V
and is 30 V for over-voltage.
If the device is in IO-Link operation, the under-voltage state
occurs at 18 V and at 30 V for over-voltage.

Tab. 5-41: Voltage and current monitoring – ISDU
Voltage Monitoring Detection Time Duration
This parameter is used to define how long the under-
voltage or over-voltage must be present before it is
displayed. The unit is given in milliseconds. The values
must be in the range between 10 and 1000, in increments
of 5 milliseconds. The default value is 10 milliseconds.
