4.15.30.9.3 Digital outputs
The output status is transferred to the output channels with a fixed offset (<60 µs) in relation to the network cycle
(SyncOut).
4.15.30.9.3.1 Switching state of digital outputs 1 to 16
Name:
DigitalOutput or
DigitalOutput01 to DigitalOutput16
The switching state of digital outputs 1 to 16 are stored in this register.

The "packed outputs" setting in the AS I/O configuration is used to determine whether all of these registers' bits
should be set up individually as data points in the AS I/O mapping ("DigitalOutput01" through "DigitalOutput16") or
whether these registers should be displayed as an individual UINT data point ("DigitalOutput").
4.15.30.9.4 Monitoring status of the digital outputs
On the module, the output states of the outputs are compared to the setpoint states. The control of the output
driver is used for the setpoint states.
A change in the output state resets monitoring for that output. The status of each individual channel can be read.
A change in the monitoring status generates an error message.
