<p>This fieldbus coupler connects the WAGO I/O System as a slave to the PROFIBUS fieldbus.</p><p>The fieldbus coupler detects all connected I/O modules and creates a local process image. This process image may include a mixed arrangement of analog (word-by-word data transfer) and digital (bit-by-bit data transfer) modules.</p><p>The process image can be transferred via the PROFIBUS fieldbus to the memory of the control system.</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 PROFIBUS to a control system for further processing. The process output data is sent via PROFIBUS.</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>
