System Description
2.1.1.6 Process
Image
The analog input module 750-483 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 14 bit resolution on bit B1 ... B14.
The states of the two first least significant bit B0 are not defined in the range
from 0 V to 30 V.
Therefore, they are represented with a ‘X‘ in the table.
The hexadecimal and decimal measured values are listed in the table assuming
