18.1.13) determines which of these variables are actually handled by the PLC; for example, if DIDO1 is set
as an input and DIDO2 as an output, DI3 and DO4 will be handled while DI4 and DO3 will not be used.
Moreover, while the variables corresponding to the inputs are updated by the PLC regardless of their
function modes, only the variables corresponding to the outputs set as “General Output” will actually affect
the digital outputs.
The second profile, named “ZPASS_GPS”, provides variables corresponding to the information given by the
GPS module, as shown in the following figure.
In particular, the GPS_ERROR variable tells if the other variables contain valid and updated values or not, in
the following way:
- GPS_ERROR = 0
GPS fixed; variables contain updated values
- GPS_ERROR = -1 GPS not fixed; variables contain not updated, possibly invalid, values
- GPS_ERROR = -2 some error has occurred; variables contain invalid values
8.1.4 Z-TWS4-IO profile
The “ZPASS_DIO” profile is available also for Z-TWS4-IO, providing variables corresponding to the available
Digital I/Os, as shown in the following figure.
