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:

Event IO-Link event
The value corresponds to attribute 20 of event log object 65 (0x41).
0: The port has no IO-Link event.
