System Description 

The analog output module 750-553 transmits 16-bit data and 8 status bits per 
channel. 

The digitalized output value is transmitted in a data word (16 bits) as output 
byte 0 (low) and output byte 1 (high) via the process image of the coupler / 
controller. 
This value is represented with a 12 bit resolution on bit B3 ... B14. 
The three least significant bits (B0 ... B2) are not parsed. 

Some fieldbus systems can process the status information using by means of a 
status byte. 
However, processing of the status byte via the coupler / controller is optional, 
which means that accessing or parsing the status information depends on the 
fieldbus system. 

For the standard module 750-553, the numerical values ranging from 0x0000 
to 0x7FFF are scaled on the output current ranging from 0 mA to 20 mA.
