PROFIBUS-DP connectors

There are many manufacturers of PROFIBUS-DP connectors. Always ensure that any
connectors used on the network are fully approved for use with PROFIBUS-DP. Some
of the connector types available include built in termination that allows the network to be
isolated, this can be very useful when fault finding. For data rates above 1.5Mbs
connectors fitted with integrated inductors should be used.
