BC2000 | Lightbus Bus Terminal Controller

The Bus Terminal Controller BC2000 is a Bus Coupler with integrated PLC functionality and has a fieldbus interface for the Lightbus. The BC2000 is an intelligent slave and can be used as a non-central intelligence in the Lightbus system. One unit consists of the Bus Terminal Controller, any number of terminals between 1 and 64, and a bus end terminal. The Bus Terminal Controller is programmed using the TwinCAT programming system according to IEC 61131-3. The configuration/programming interface of the BC2000 is used to load the PLC program. If the software PLC TwinCAT is in use, the PLC program can also be loaded via the fieldbus.

The inputs and outputs of the connected Bus Terminals are assigned in the Bus Terminal Controller’s default setting. Each Bus Terminal can be configured in such a way that it exchanges data directly through the fieldbus with the higher-level automation device. Similarly, pre-processed data can be exchanged between the Bus Terminal Controller and the higher-level controller via the fieldbus.

Controller for distributed signal processing

The programming system TwinCAT for the BC2000 operates, independently of the manufacturer, in accordance with IEC 61131-3. The PLC programs can be written in five different programming languages (IL, FBD, LD, SFC, ST). In addition, TwinCAT offers extensive debug functionalities (breakpoint, single step, monitoring, …), which facilitate commissioning. It is also possible to perform adjustment and measurement of the cycle time.
