System Description 

 

2.1.1.7 Process Image 

Some fieldbus systems can process input channel status information by means 
of a status byte. 
This status byte can be displayed via the starting tool WAGO-I/O-CHECK 2. 
However, processing via the coupler / controller is optional, which means that 
accessing or parsing the status information depends on the fieldbus system. 

 

Attention 

The representation of the process data of some I/O modules or their variations 
in the process image depends on the fieldbus coupler/-controller used. Please 
take this information as well as the particular design of the respective 
control/status bytes from the section "Fieldbus Specific Design of the Process 
Data" included in the description concerning the process image of the 
corresponding coupler/controller.
