Input register
Function code "04" to read the information.
Validity of the measured value stored in the INPUT register
addresses 1…3:
It can be seen via the DISC register address with address 4
(Boolean) whether the measured value is invalid (0) or valid
(1). We recommend evaluating this register address alongside
the measured value query.
Device status:
The INPUT register address0 indicates the device status (0:
the device self-diagnostic could not find any errors). We rec-
ommend querying the device status either parallel to the mea-
sured values or when needed (e.g. during troubleshooting,
fault elimination).
For details, see Fault elimination.
