Instead of having to offer multiple variants to suit a large number of industrial fieldbuses, such as Profibus DP, DeviceNet, AS-i and so on, ABB is now able to offer control equipment such as its new FBP motor controllers and starters in one standard version with a neutral fieldbus-independent interface called the FieldBusPlug (FBP).
All the installer has to do is attach the appropriate ready-made bus-specific FBP connection cable to suit their fieldbus.
The FBP FieldBusPlug establishes the connection of the individual switching and automation devices to the process controller. The design of the plug is very simple. A fieldbus-neutral plug is fitted at one end of the cable and a plug with the fieldbus-dependent interface is located at the other end.
Intelligent electronics have been built into a compact plug to convert the neutral device data into a language which the process fieldbus (such as AS-I or DeviceNet) can understand. ABB will offer plugs to suit all the major fieldbuses on the market.
A major advantage of the FBP concept is that ABB is not inventing its own additional bus, but is using the many fieldbuses already available. Also, since it is an open system, the FBP can embrace any PLC system used by a customer.
Because ready-made plug-in connectors are used to attach the device to the fieldbus and the supply voltage, there is no need to cut, isolate and prepare cables.
