BC9020, BC9050 und BC9120 - Overview
The BC9xx0 series Bus Terminal Controllers have an Ethernet interface and offer a high degree of flexibility. They can also be operated in stand-alone mode.
The BC family Bus Terminal Controllers consist of a programmable IEC 61131-3 controller and the K-Bus interface for the connection of the Beckhoff Bus Terminals and a Ethernet interface.
The Bus Terminals can be connected directly in the usual way. The comprehensive range of different I/Os enables any input signal to be read and any output signal that may be required to be generated. This small controller therefore enables a wide range of automation tasks to be solved, from garage door controllers to autonomous temperature control at injection molding machines. The BC family is also particularly suitable for a modular machine concept. Within a network, the Bus Terminal Controller can exchange data with other machine components via the fieldbus interfaces.
 | Bus Terminals required At least one Bus Terminal with process image and one end terminal must be connected to the K-bus of the Bus Terminal Controller. |
Fieldbus interface
The variants of the BC9xx0 series Bus Terminal Controllers have different fieldbus interfaces (with and without switch) and different maximum program size.
Programming
The BC devices are programmed according to the powerful IEC 61131-3 standard. As with all other Beckhoff controllers, the TwinCAT automation software is the basis for parameterization and programming. Users therefore have the familiar TwinCAT tools available, e.g. PLC programming interface and System Manager. Data exchange is optionally via the serial port (COM1) or via Ethernet.
Configuration
The configuration is also carried out using TwinCAT. The fieldbus interface can be configured and parameterized via the System Manager. The System Manager can read all connected devices and Bus Terminals. After the parameterization, the configuration is saved on the BC via the serial interface. The configuration thus created can be accessed again later.
| Required TwinCAT version BC9020, BC9050, BC9120 are supported from TwinCAT 2.10 build 1322. |
