Module Data, Status, and Channel Configuration
for Analog Output Modules
This chapter examines the analog output module's output data file and
configuration.
Analog Output Image
The output image file represents data words. Output words 0 and 1 hold the
output data that represents the value of the analog outputs for channels 0
and 1. Analog output data is presented as raw or proportional.
Output words 2 and 3 contain output data for two optional discrete output
expansion modules.
Analog Output Data File
The structure of the output data file is shown.
