Analog inputs: I7 – I8
The values of both analog inputs I7, I8 (only EASY...-DC-..)
are read with the following command.
Analog inputs I7 and I8 (byte 1 and byte 2)
These two bytes contain the process variable of the analog
inputs I7 and I8. Their value lies between 00 and 99, which
is equivalent to a voltage level of 0 to 9.9 V at the inputs. The
corresponding values are returned in hexadecimal format.
