4.15.23.9.4.1 Status of digital outputs 1 to 8
Name:
StatusInput01
StatusDigitalOutput01 to StatusDigitalOutput08
This register is used to indicate the status of digital outputs 1 to 8.
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 ("StatusDigitalOutput01" through
"StatusDigitalOutput0x") or whether this register should be displayed as an individual USINT data point
("StatusInput01").

4.15.23.9.5 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
It should be noted that very fast cycles decrease the idle time available for handling monitoring, diagnostics and
acyclic commands.
Minimum cycle time
100 μs
4.15.23.9.6 Minimum I/O update time
The minimum I/O update time defines how far the bus cycle can be reduced while still allowing an I/O update to
take place in each cycle.
Minimum I/O update time
Equal to the minimum cycle time
