<p>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.</p><p>The system supply is provided directly by the coupler. The field supply is provided via a separate supply module.</p><p>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.</p><p>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.</p><p>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.</p>
