BC7300 | Modbus Bus Terminal Controller

The Bus Terminal Controller BC7300 is a Bus Coupler with integrated PLC functionality and has a fieldbus interface for Modbus. The BC7300 is an intelligent slave and can be used as a non-central intelligence in the Modbus system. One unit consists of the Bus Terminal Controller, any number of terminals between 1 and 64, and a bus end terminal. Because of the low baud rate used by the Modbus protocol, use of the BC7300 may be of value to reduce the bus communication. Time-critical connections can also be programmed directly at the Bus Terminal Controller.

The Bus Terminal Controller is programmed using the TwinCAT 2 programming system according to IEC 61131-3. The configuration/programming interface on the BC7300 is used to load the PLC program.

The inputs and outputs of the connected Bus Terminals are assigned in the PLC’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. Configuration is performed using the KS2000 configuration software.

Controller for distributed signal processing

The programming system TwinCAT for the BC7300 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.
