Pepperl+Fuchs has developed the new FieldConnex fieldbus diagnostic handheld device (FDH-1) that uses a quick and simple method to display the quality of the fieldbus installation. The handheld has been specifically designed to be easy to operate without the need for expert fieldbus knowledge. To connect the handheld to any fieldbus segment, PC is not required. This connection enables the handheld to show whether or not there are any errors in the physical layer installation prior to commissioning a segment. If there are errors, it will pinpoint what they are, where they are, and how they can be corrected. This saves time and money during installation. The FDH-1 can also be used to check existing cables in order to determine whether they are suitable for a fieldbus installation. Taking this approach can lead to considerable savings in terms of cabling costs and the amount of maintenance work required, ensuring reliable operation of the fieldbus. In existing installations, the FDH-1 can check the short-circuit protection at the spur connections.
