Page 8: Product Overview
Microsoft Windows CE is used as the operating system. In the absence of a monitor port, the operating system and its "virtual" display can only be accessed via the network. As for all other Beckhoff devices, the TwinCAT software is used for system configuration and the programming of the PLC functionality. The CX80xx target device features a pre-installed TwinCAT PLC runtime environment. - Page 9 The CX80xx controller is programmed according to the high-performance IEC 61131-3 standard. As with all other Beckhoff controllers, the TwinCAT automation software is the basis for parameterization and programming. Users therefore have the familiar TwinCAT tools available, e.g. PLC programming interface, System Manager and TwinCAT Scope.

Dimensions The following drawings show the dimensions of the CX80xx Embedded PCs. Dimensions Drawings in various CAD formats can be found at: http://www.beckhoff.de/german/download/cx1000.htm 3.1.2 Installation on mounting rails Snapping onto the mounting rail The CX80xx can simply be snapped onto the mounting rail. To this end simply position the block on the mounting rail and push it slightly until it engages on the right-hand side. - Page 14 Ventilation openings are located at the top and bottom of the housing. The system therefore has to be installed horizontally. This ensures optimum air flow. Installation positions with reduced temperature range up to 45 °C Other installation positions are permitted with a temperature range up to 45 °C. Version: 1.0.0 CX8080...

WARNING 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 with the designation 24 V and 0 V. The supply voltage supplies the CX system and, via the terminal bus, the Bus Terminals with a voltage of 24 (15 %/+20 %). -

10Base2 (Cheaper net) is a further development of 10Base5, and has the advantage that the coaxial cable is cheaper and, being more flexible, is easier to lay. It is possible for several devices to be connected to one 10Base2 cable. It is frequent for branches from a 10Base5 backbone to be implemented in 10Base2.

CX8080 is scanned, and it then adds the two serial interfaces automatically in your system. Start your CX8080 in Config mode. The TC LED of the CX8080 must then turn blue. Now you can scan for new devices. - Page 28 KS8000 protocol for operation of the Bus Coupler BK8100 or BK8000 Both interfaces can be used as BK8xx0 master. It is an open Beckhoff protocol, which should be used for the products BK8100 RS232 or BK8000 RS485. The protocol is already implemented, and you can address the couplers directly.
- Page 29 A further setting is the KL6xx1 mode. It should be used for all other protocols. In conjunction with the supplements ModbusRTU, IEC 60870 or other serial protocols, the interface can then support different serial protocols. Proprietary protocols or other open protocols can also be used (see Programming [} 42]). CX8080 Version: 1.0.0...

In KL6xx1 mode, any serial protocols can be implemented. To this end, configure the interface as KL6xx1 mode in the System Manager. This mode behaves like the serial interface terminals from Beckhoff. It only means that the programming and the interface is similar to a serial interface. The Beckhoff supplement blocks (such as ModbusRTU, COMLIB, ...) of the serial interface usually offer the 64-byte mode for the PC interface. - Page 43 SW.0 (TA).
