FIELD BUS COUPLER FOR CONNECTING INPUT/OUTPUT MODULES TO A FIELD BUS, AND METHOD OF OPERATION FOR A FIELD BUS COUPLER

摘要

The present invention relates to for operating field bus coupler (3), for connecting input/output module (5) to fieldbus (2) industrial automation system via bus (4), in normal manipulation mode, at least one input/output module (5) that field bus coupler (3)-receives the output channel of output valve (one) passes through fieldbus (2), and transfer it to input/output module (5) via bus (4) and/or-receive input value (E) and at least one input/output module (5) via bus (4) and by it via fieldbus (2). The method the difference is that, diagnostic mode, field bus coupler (3)-transmit at least one input/output module (5) of the output channel of at least one given output valve (*) to input/output module (5) via bus (4) and/or-are associated at least one given input value (condition) and at least one input/output module (5) and by it via fieldbus (2). The invention further relates to a kind of field bus coupler (3) devices used to perform the method.
