Voltage and Current Monitoring
6.8.1
Description
The voltage and current module sends messages about
over-current, short-circuit, wire breakage, over-voltage and
under-voltage. Over-voltage and under-voltage detection
starts a timer. If the timer has expired and the voltage level
has not returned to the normal operating voltage threshold,
the module sends out the messages.
The messages include device status, IO-Link events,
process data and LED signaling.
6.8.2
Mathematics/Algorithm
In SIO operation, the threshold for undervoltage is 9 V and
is 31 V for overvoltage.
If the device is in IO-Link operation, the undervoltage state
occurs at 16 V and the overvoltage state occurs at 31 V.

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.

Description
TRUE = overload or short-circuit detected at pin 2.
TRUE = the voltage level is below the threshold value.
TRUE = the voltage level is above the threshold value.
TRUE = cable break detected at pin 2.
TRUE = overload detected at pin 2.
