Fixed modules require their data points to be in a specific order in the X2X frame. Cyclic access occurs according
to a predefined offset, not based on the register address.
Acyclic access is continues to be based on the register numbers.

The offset specifies where the register is within the CAN object.
4.15.21.9.3 Digital outputs
The output status is transferred to the output channels with a fixed offset (<60 µs) in relation to the network cycle
(SyncOut).
4.15.21.9.3.1 Switching state of digital outputs 1 to 6
Name:
DigitalOutput
DigitalOutput01 to DigitalOutput06
The switching state of digital outputs 1 to 6 are stored in this register.
Function model 0 - Standard only:
The "packed outputs" setting in the AS I/O configuration is used to determine whether all of this registers' bits
should be set up individually as data points in the AS I/O mapping ("DigitalOutput01" through "DigitalOutput0x") or
whether this register should be displayed as an individual USINT data point ("DigitalOutput").
