System Description
2.1.1.6

Process Image

The analog input module 750-479 transmits 16-bit measured values and
8 optional status bits per channel.
The digitalized measured value is transmitted in a data word (16 bits) as input
byte 0 (low) and input byte 1 (high) into the process image of the coupler /
controller.
This value is represented with a 13 bit resolution on bit B2 ... B14 and the sign
bit is represented on bit B15.
The states of the two first least significant bits B0 and B1 are not defined in
the range from –10 V to +10 V.
Therefore, they are represented with an 'X' in the table.
The hexadecimal and decimal measured values are listed in the table assuming
that the first two bits have the state '0'. When both bits have the state '1', the
value 3 is added to the decimal measured value indicated in the table.
