4.15.24.8.3.3 Switching between inputs and outputs
Name:
EnableDigitalOutput
EnabDigitalOutput01 through EnabDigitalOutput08
In this register, all channels can be connected as inputs or outputs. For each output there is a corresponding
switching bit. Clearing this bit switches to tristate mode.
In function model 254 the initial value is 255.
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 ("EnabDigitalOutput01" through "EnabDigitalOutput08")
or whether this register should be displayed as an individual USINT data point ("EnableDigitalOutput").

4.15.24.8.4 Digital inputs
Name:
DigitalInput
DigitalInput01 through DigitalInput08
The status of digital inputs 1 to 8 is mapped in this register.
The status of the digital inputs is read with a minimum update rate of 5 to 8 msec. according to the digital output
status sample rate.
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 ("DigitalInput01" through "DigitalInput0x") or
whether this register should be displayed as an individual USINT data point ("DigitalInput").
