4.15.6.14.8 Status of the outputs
Name:
LowCurrentStatus1 through LowCurrentStatus2
ZeroCrossingInput
ZeroCrossingStatus
StatusInput01
The operating status of the outputs is mapped in this register.
In order to do determine the "LowCurrentStatus", the system checks if there is a neutral connection from the output
via the consumer shortly before each triac firing.
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 ("LowCurrentStatus1" through "ZeroCrossingStatus")
or whether this register should be displayed as an individual USINT data point ("StatusInput01").
