Secondary Device Functions (continued)
5.9 Voltage and Current Monitoring
5.9.1 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 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.
5.9.3 Process Data
Object ID Name Description Direction
0x0016 (22) Overload / short-circuit
pin 2
TRUE = overload or short-circuit detected at pin 2. Input
0x0017 (23) Undervoltage TRUE = the voltage level is below the threshold value. Input
0x0018 (24) Overvoltage TRUE = the voltage level is above the threshold value. Input
0x001A (26) Cable break pin 2 TRUE = cable break detected at pin 2. Input
0x0044 (68) Overload pin 2 TRUE = overload detected at pin 2. Input

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.
