Notes on the documentation
8 CX50x0 - Hardware Documentation
The complete programming of PLC, Motion Control and visualisation is transferable to all PC controls from Beckhoff,
which is reassuring in cases where it becomes apparent during a project that more processing power is required after
all. In this case a system with higher performance can be used.
Fieldbus interfaces
The fieldbus interfaces are currently available as master and slave versions for the following field busses:
Optional interfaces:
The optional interfaces can be used to connect single-channel fieldbus interfaces. Operation is limited to one
interface at a time. If several fieldbus interfaces are required, they can be added as E-bus terminals (EL67xx). The
following fieldbus interfaces are available:
 CX50x0-N030 = RS232, D-Sub connector

CX50x0-N031 = RS422/RS485, D-Sub socket
 CX50x0-M310 = PROFIBUS master, D-Sub socket, 9-pin
 CX50x0-B310 = PROFIBUS slave, D-Sub socket, 9-pin
 CX50x0-M510 = CANopen master, D-Sub connector, 9-pin
 CX50x0-B510 = CANopen slave, D-Sub connector, 9-pin
 CX50x0-M930 = PROFINET RT, controller, Ethernet (2 x RJ-45 switch)
 CX50x0-B930 = PROFINET RT, device, Ethernet (2 x RJ-45 switch)
 CX50x0-B951 = Ethernet/IP slave, Ethernet (2 x RJ-45 switch)
 CX50x0-B100 = EtherCAT slave, EtherCAT IN and OUT (2 x RJ 45)
The software
In combination with the TwinCAT automation software, the CX50x0 Industrial PC becomes a powerful IEC 61131-3
PLC with up to four user tasks. Additionally, Motion Control tasks can also be executed. Depending on the required
cycle time, several servo axes can be controlled. Even special functions such as flying saw, electronic gearbox and
cam plate can be realised.
The CX50x0 system is programmed in the same way as other bus controllers:
Remote programming via Ethernet
This option is used if the basic unit is equipped with “Windows CE.NET”. In this case, the system is programmed via
a laptop or a desktop PC, which is connected to the CX via Ethernet (network or crossover cable). The programs are
developed on the laptop with a standard TwinCAT software license and then loaded into the target device.
Visualisation
The Beckhoff OPC server is available for interfacing with SCADA packets, if the two operating system variants
“Windows CE.NET” or “Windows XP Embedded” are used. In other words, the CX50x0 also offers straightforward
visualisation and simultaneous control in real-time on a single system.
