16.5.5 Monitoring status of the digital outputs
The error states of the outputs must be programmed in the application. The status information that is read is the
actual voltage state on the channel (set or reset). The error state is therefore determined by a difference between
the data points "DigitalOutputxx" and the corresponding "StatusDigitalOutputxx".
At least 3 system ticks are needed internally to read the output status. This is the reason for the delay after which
the earliest possible comparison can be made after a change in the status of the output.
The digital input filter is not applied to this status information.
