Page 8: Product Overview
Notes on the documentation 2. Product overview Intended use The CX5010 / CX5020 device series is a modular control system designed for top-hat rail installation. The system is scalable, so that the required modules can be assembled and installed in the control cabinet or terminal box as required. -
Page 9: System Overview
EtherCAT Terminals. Two independent Gigabit Ethernet ports and four USB 2.0 interfaces are available. A Beckhoff control panel or a commercially available DVI monitor can be connected to the DVI D interface. A serial port (RS232/RS422/RS485) or a fieldbus connection with master or slave function can be added as an optional interface as required. - Page 10 Notes on the 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.

Notes on the documentation Overview This library contains functions and function blocks which are needed in order to use the Seconds UPS. See sample project Sample_S_UPS.pro. Function Blocks Name Description FB_S_UPS Function block to use the Seconds UPS from the PLC. FB_NT_QuickShutdown Internal function block for the QuickShutdown, used by the FB_S_UPS. - Page 20 In case of the EWF the TwinCAT\Boot folder needs to be located on a not protected partition (see in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Beckhoff\TwinCAT\System\BootPrjPath). In case of the FBWF the TwinCAT\Boot folder needs to be excluded from the protection (see Beckhoff FBWF Manager, Exclusion Settings).

Page 30: Assembly On Mounting Rail
Notes on the documentation Installation on the mounting rail Snapping onto the mounting rail The CX50x0 can simply be snapped onto the mounting rail. To this end position the block on the mounting rail and push it slightly until it engages on the right-hand side. The is indicated by a distinct click. Use a screwdriver to push up the lock on the left-hand side, thereby turning it and causing it to engage audibly. - Page 31 Notes on the documentation Incorrect installation positions The CX50x0 system must not be operated vertically on the top-hat rail. A vertical position would lead to insufficient CPU ventilation, since the ventilation openings are located on the top and bottom of the housing. Installation of the system on its side would also lead to inadequate ventilation.

Page 32: Power Supply
Notes on the documentation Power supply This power supply unit is equipped with an I/O interface, which permits connection of the Beckhoff Bus Terminals. The power is supplied via the upper spring-loaded terminals labeled “24V” and “0V”. The supply voltage supplies the CX system ant the terminal Bus and Bus Terminal with a voltage of 24 V DC (- 15 %/+20 %). - Page 33 Notes on the documentation UL requirements Danger For the compliance of the UL requirements the CX-Controllers should only be supplied by a 24 V supply voltage, supplied by an isolating source and protected by means of a fuse (in accordance with UL248), rated maximum 4 Amp. ...
-
Page 34: Dvi-D Connection
The DVI-D interface transfers digital data and is suitable for connecting a digital display. The resolution at the display or the Beckhoff Control Panel depends on the distance from the display device. The maximum distance is 5 m. DVI-D interface The DVI interface does not use VGA signals, so that the connection of CRT VGA monitors to the CX1000 system using a DVI to VGA adapter is not possible. -
Page 35: Usb Connections
Notes on the documentation USB connections USB interface (X100 / X101 / X102 / X103): The CX50x0 has 4 independent USB interfaces, for connecting keyboards, mice, touch screens and other input or data storage devices. Keep an eye on the power consumption of the individual devices. Each port is limited to 500 mA. -
Page 36: Lan Connections
Notes on the documentation LAN connections LAN interface (X000/ X001) The CX50x0 systems have two independent LAN interfaces. Both ports are able to operate at speeds of 10 / 100 / 1000 Mbit. The LEDs on the left-hand sides of the RJ45 sockets indicate the status of the LAN connection. The upper LED indicates whether the port is connected to a network. -
Page 37: Rs232 Connection
Notes on the documentation RS232 connections (CX50x0-N030) The CX50x0-N030 system interface provides an RS232 interface, COM1 (X300). It is implemented on a 9-pole Sub- D pin strip. If more than one interface is required the system can be extended via the Terminal Bus (K- or E-bus) or Bus Terminals (KL/EL6001) which provide serial interfaces. -
Page 38: Rs422/Rs485 Connection
Notes on the documentation RS422/RS485 connections (CX50x0-N031) The CX50x0-N030 system interface provides an RS422 or RS 485 interface, COM1 (X300). It is implemented on a 9- pole Sub-D socket strip. If more than one interface is required the system can be extended via the Terminal Bus (K- or E-bus) or Bus Terminals (KL/EL6021) which provide serial interfaces. -
