Structure of process data input
The Process Data Input (the measured data of EE741) is configurable and structured in the following
order:
Bit no.
Process data input

Tab. 10
Scheme of process data input
Per factory default, the measurands' data type is FLOAT32 (more exactly, 32 bit single precision float). The
parameters may freely be selected via IO-Link device parameter, the most usual are pre-selected per default. See
Tab. 11 for the supported measurands.
Alternatively, the measured data may be represented as INT32 within the above scheme, the values are scaled
with a factor 1 000 in this case.
PLEASE NOTE
Please note that the data type selection (FLOAT32 or INT32) applies to the entire 12 byte process data
input, i.e., all 3 measureands will have the same data type at the same time.
