<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></p><p>The system supply is provided directly by the coupler. The field supply is provided via a separate supply module.</p><p></p><p>The Device<b>Net</b><sup></sup> Fieldbus Coupler detects all connected I/O modules and creates a local process image.</p><p></p><p>The process image can be transferred via the Device<b>Net</b><sup></sup> fieldbus to the memory of the control system.</p><p></p><p>The local process image is divided into two data zones containing the data received and the data to be sent. The process data can be sent via the Device<b>Net</b><sup>TM</sup> to a control system for further processing. The process output data is sent via Device<b>Net</b><sup>TM</sup>.</p><p></p><p>The data of the analog modules is stored in the process image that is created automatically according to the order in which the modules are connected to the coupler. The bits of the digital modules are sent byte by byte and added to the analog data. If the amount of digital I/O information exceeds eight bits, the coupler automatically starts with a new byte.</p>
