Page 13: 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. -
