Product overview Product overview Intended use The CX20x0 device series is a modular control system designed for DIN 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.
USB Extended interface. The CX2550-0179 system module is suitable for the connection of the Beckhoff CP69xx and CP79xx Control Panel series with USB Extended 1.1 connection. The CX2550-0279 system module is suitable for the connection of the Beckhoff CP29xx and CP39xx Control Panel series with USB Extended 2.0 connection.

5. Check the contents for visible shipping damage. 6. If you notice any shipping damage or inconsistencies between the contents and your order, you should notify Beckhoff Service. Danger of damage to the device! During transport in cold conditions, or if the device is subjected to extreme temperature dif- ferences, condensation on and inside the device must be avoided.
Mounting and wiring Dimensions The following drawings show the dimensions of the CX2550-0x79 interface. Both variants CX2550-0179 (USB1.1) and CX2550-0279 (USB 2.0) have the same dimensions Dimensions CX2550-0179 / CX2550-0279 Version: 1.0...
Mounting and wiring Attaching the system interface to the CX20x0 system The USB extension is positioned directly between the CPU and the power supply unit. When the module is connected to the CPU it engages audibly. Further modules can be connected to the system in the same way. Please note that some modules are connected on the left-hand side of the CPU.
Page 15
Mounting and wiring Avoid damage! Do not force the module or apply excessive pressure! Attention Installation position Comply with the permitted installation position and minimum distances! The maximum ambient temperature for CPU modules mounted on a DIN rail is 60°C. The orientation in which the device is fitted must be selected in such a way that cooling air can Attention flow vertically through the ventilation holes.
Page 16
Mounting and wiring Incorrect installation positions The CX20x0 system must not be operated vertically on the DIN 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.
Mounting and wiring Mounting the module lock Mounting the lock The CX20x0 controller system is fully modular, i.e. all system interfaces of the system are field-configurable. As a rule the latching of the modules to each other is sufficiently strong. However, it is possible for the controller and its modules to be exposed to vibrations, shocks or impacts.

Mounting and wiring USB connection RJ 45 interface for CX2550-0179 (USB1.1) (X179): EtherCAT cable, category CAT5e. Table 1: Assignment of RJ 45 interface: Signal Description 15 V 15 V + Ground USB TX USB RX USB RX USB TX 15 V 15 V + Ground the LEDs of the RJ 45 sockets are redundantly implemented on the lower dagnostic LEDs [} 25].
Minimum requirements: 1. EtherCAT redundancy supplement 2. EK1110 (Bus extension) 3. EK1100 (Bus Coupler) The supplement product on the Beckhoff website at http://download.beckhoff.com/download/Software/TwinCAT/TwinCAT2/Supplement/ TwinCAT_EtherCAT_Redundancy/Install/TcEcRedundancy.exe can be downloaded. The required licence key can be ordered from our sales division. The required couplers are ordered together with the other hardware.

This supplement only supports cable redundancy. This means that fail safety exists only for the cable sections. That means the connections between the couplers. Failures of individ- Note ual terminals are not covered.Further details can be found in the Beckhoff Information Sys- tem under EtherCAT cable redundancy. Cases of failure The two possible failures are described in the example below.

Commissioning / Configuration The interruption is indicated by "LNK_MIS B" and "LNK_MIS A". The next example shows a failure of the "return line": In this case the second cable is faulty. The terminals at the coupler continue to run without malfunction. The System Manager indicates the behaviour as follows: Version: 1.0 CX2550-0179 / CX2550-0279...
Commissioning / Configuration The interruption is indicated by "LNK_MIS C" at coupler EK1100. The EtherCAT ring is expandable. The number of devices in the ring is controlled by licenses: up to 250, up to 1000, more than 1000. A master is only able to bridge one failure. In the event of two failures the ring components will continue to run up to the breaking points.
USB hub to the USB device. Via the USB extension a Beckhoff Touch Panel can be connected. Thus a panel of type CP69xx/79xx can be operated up to 50 meters from the CX system without additional devices.

Decommissioning Decommissioning Disassembly and disposal The disassembly of a CX20x0 hardware configuration with system interfaces takes place in 3 steps 1. Switching off and disconnecting the power supply Before a CX20x0 system can be dismantled, the system should be switched off, and the power supply should be disconnected.
