Overview

The TwinCAT PLC library, COMlibBC, offers function blocks and data structures for serial data communication with the Beckhoff BCxxxx bus controllers. COMlibBC supports the Beckhoff KL6xxx serial bus terminals.

In addition to the basic functions of sending and receiving transparent data, COMlib3964RBC supports the 3964R protocol. Both libraries are included in the 3964R package.

This documentation is to be seen as a supplement to the documentation COMlibBC.
