5.2 Forcing

This section describes the "Force" function for the module's input and output data.
In forcing, the physical states of the inputs or the output values of the higher-level con-
troller are "forcibly" overwritten with other values. The user provides these values and
identifies them as forcing values. This method is helpful for commissioning systems and
troubleshooting.
The "Forcing" function can be accessed through the following tools:
• WAGO I/O Field Webserver
• WAGO I/O Field app on mobile devices
Systems like SPS, TIA Portal and the like also have forcing functions. Such forcing func-
tions should not be confused with the ones described in this section and will not be con-
sidered within the context of this section.
A distinction is made between two types of forcing:
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.
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.
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
"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.
The functional scope described can vary depending on the module type.
