The ECO Fieldbus Coupler is designed for applications with a low data width in the process image. These are primarily applications that use digital process data or only low volumes of analog process data.
The system supply is provided directly by the coupler. The field supply is provided via a separate supply module.
When initializing, the coupler determines the node's module structure and creates the process image of all inputs and outputs. In order to optimize addresses, I/O modules with a bit width smaller than eight are grouped in one byte.
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.
