Standard Format - WAGO I/O System 750 750-483 Manual

that the first two bits have the state '0'. When both bits have the state '1', the
value 1 is added to the decimal measured value indicated in the table.
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.
