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

    Thus, 0 °C corresponds to the numeric value 0x0000 and 100 °C to 0x03E8 (dec. 1000). Temperature values below 0 °C are represented in two’s complement binary form. The measured values of the resistance are directly sent by the 750-461/000- 200 (Pt 100) module. WAGO-I/O-SYSTEM 750 I/O Modules...

    Measuring range: 10 Ω ... 5.0 kΩ The measured values are sent out directly when measuring the resistance. Using the 750-461/000-002 module with measuring range from 10 Ω to 1.2 kΩ, the resolution is 1 digit per 0.1 Ω. Using the 750-461/000-007 module with measuring range from 10 Ω to 5.0 kΩ, the resolution is 1 digit per 0.5 Ω.
