The BX5100 Bus Terminal Controller has a CANopen slave interface. It has automatic baud rate
detection up to 1 Mbaud and an address selection switch for address assignment. Up to 16 Tx PDOs
and 16 Rx PDOs can be exchanged with the control.
One unit consists of the BX5100 Bus Terminal Controller with up to 64 Bus Terminals and a bus end
terminal. With the terminal bus extension system, the connection of up to 255 Bus Terminals is
possible. The controller is programmed via the COM1 or via the CANopen interface of the FC510x PC
Fieldbus Card.

In terms of their equipment and performance, the BX series Bus Terminal Controllers are positioned
between the BC series Bus Terminal Controllers and the CX series Embedded PCs. The main features
distinguishing BC and BX are the larger memory and the expanded interfaces of the BX. Additionally,
two serial interfaces are integrated for programming and for the connection of further serial devices.
The device itself comprises an illuminated LC display with two lines of 16 characters each, a joystick
switch and a real-time clock. Further peripheral devices, e.g. displays, can be connected via the
integrated Beckhoff Smart System Bus (SSB).
The BX family is particularly suitable for a modular machine concept. Within a network, the Bus
Terminal Controller can exchange data with other system parts via the fieldbus interfaces. The real-
time clock enables decentralized applications, for which the day of the week or the time play an
important role. The areas of application of this series are similar to that of the BC series, but due to
the larger memory the BX can execute significantly more complex and larger programs and can
manage more data locally (e.g. history and trend data recording), which are then successively fetched
over the fieldbus.
