Functions
1. Input simulation means overwriting input data with replacement values.
2. Overwriting output data with replacement values means setting or resetting the mod-
ule outputs independent of the module's process image.
Forcing Outputs
To force output data for test purposes, you can control all the outputs independent of the
actual process data value and set them to a specified alternative value.
For digital outputs, you can force pin 2 and pin 4.
For IO-Link, you can force port 16 data bytes.
Simulating Inputs
To simulate input data, you can set alternative values that are used for the input instead
of the actual process data values. This allows you to test how the system (i.e., the mod-
ule and a connected controller) responds to specific inputs.
With digital inputs, you can simulate pin 2 and pin 4.
For IO-Link, you can simulate port 16 data bytes.
Simultaneous Access
A device-internal mechanism prevents simultaneous access by multiple instances. This
ensures that only one single instance at a time ever has write access.
"Forcing" Operating Mode Must Be Enabled in the Parameterization
The "Forcing" operating mode can be switched off by the higher-level controller. This is
done with the "Force mode setting" parameter – see
enable forcing, the "Force mode setting" parameter value must be set to 0 ("Enable force
mode"). This is the default setting in the device description file provided with the device.

5.3 Monitoring Functions

The 765 Series modules have extensive internal sensors for measuring:
• Temperatures
• Currents
• Voltages
The measurements are performed for the module and for pin 1, pin 2 and pin 4 of each
port. The measured values can be displayed in the WAGO I/O Field Webserver or the
WAGO I/O Field app. Alternatively, an OPC UA client can read out the measured values
and display them.
In the module, the measured values are compared to limiting values. An alarm or event is
generated if a value falls above or below a limiting value (e.g., a temperature limiting
value). The module can send this alarm/event
• EtherNet/IP: The controller can read out the event log object (object 65, 0x41)
• to the OPC UA client upon: OPC UA: event.
The OPC UA client application can use the measured values, for example to implement
load management. You can find information on load management in section
