tem Description
2.1.1.7 Process Image
The analog input module 750-468 and its variations transmit 16-bit measured
values and 8 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 12 bit resolution on bit B3 ... B14.
From the manufacturing number |32|02|XX|XX| onwards, the status informa-
tion included in the three least significant bits (B0 ... B2) can be parsed in the
event of an error. Bit B0 = 1 is set when the range of measurement is over-
ranged.
For modules having a previous manufacturing number, the last 3 bits are not
parsed.
The manufacturing number is part of the lateral marking on the module enclo-
sure.
