System Description
2.1.1.7 Process Image
The analog output module 750-559 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.
As the returned status byte of this output module is always zero, it will not be
parsed.
2.1.1.7.1 Standard Format
For the standard module 750-559, the numerical values ranging from 0x0000
to 0x7FFF are scaled on the output current ranging from 0 V to 10 V.
