The 750-333 Fieldbus Coupler maps the peripheral data of all the WAGO I/O System's I/O modules on PROFIBUS DP.
When initializing, the coupler determines the node's module structure and creates the process image of all inputs and outputs. I/O modules with a bit width smaller than eight are grouped in one byte for address space optimization.
It is furthermore possible to deactivate I/O modules and to modify the image of the node according to the connected signals without having to modify the existing control application.
The diagnostic concept is based on ID- and channel-related diagnostics according to EN 50170. This does away with the need for programming modules to evaluate manufacturer-specific diagnostic data.
The device is ideal for operation in extreme environments thanks to:
- An extended temperature range
- Greater immunity to impulse voltages and electromagnetic interference
- Higher vibration and shock resistance
