4.11.17.12.5 Event functions
The module provides configurable event functions. An event function can be connected to physical I/O and the
values derived from them (e.g. counters) or be purely used for internal processing.
Every event function has event inputs and outputs. Event functions can also have only inputs or only outputs. Each
event output has a unique event ID. It is possible to configure when an event should be generated on an event
output. The effect of an event is determined by the respective event function.
Event functions can also be linked to one another. The link takes place using the event input. Every event input
has a 16-bit register to which the event number of the linked event output is written.
Information:
The module functions that can be configured in the AS I/O configuration are primarily based on these
event functions and their links. Changes in the AS I/O configuration have multiple effects on event
functions and their links.
