BECKHOFF CX1000 Industrial Control PC Complete Manual

Pull the white strap: There is a white strap at the bottom of each module. Use a straight screwdriver to gently pull it downwards (Figure 4) to release the locking mechanism.

Hanging the guide rail: First, hang the CPU module (connected to the system interface) onto the upper edge of the guide rail, and then press down to clamp the tension strap into the lower edge of the guide rail (Figure 5). Release the tension strap and allow it to bounce back to its initial position (Figure 6, 7).

Splicing other modules:

If you need to add a fieldbus module, first hang it on the guide rail, then align it with the PC104 interface of the CPU module from the side and push it tightly to ensure no gaps (Figure 3).

Finally, install the power module (also hang the rail and tighten it). Attention sequence: The power module should be installed on the right side of the CPU; The fieldbus module is on the left side (if any).

Remove the protective cover: If you need to connect the fieldbus module, first remove the gray protective cover on the left side of the CPU (Figure 1, 2), and then reinstall it.

Disassembly steps

Power off: Turn off the 24V power supply and disconnect all connections.

Remove the guide rail: Pull down the white strap at the bottom of all modules to release the lock. If the power module is connected to the bus terminal, the first terminal needs to be pried open from the guide rail first (Figure 2).

Separation module: Use a 1.0 × 5.5 × 150 mm flathead screwdriver to insert into the separation slot on the back of the module (Figure 4), rotate about 90 ° to create a 2-3 mm gap between the modules, and then carefully unplug the PC104 connector (Figure 5).

Warning: Forcefully prying open modules without separation slots can damage the casing.

Detailed explanation of power module and use of NOVRAM

CX1100-0001 (pure power supply)

Wiring: 5-pin open plug, pin definitions: 1=+24 V, 2=0 V, 3=GND, 4=+UPS (+24 V), 5=- UPS (0 V). Suggest using a 2A fuse (24V).

LED: PWR green - normal; Red - short circuit.

LCD: It can be controlled through the ADS port (0x000005000+DeviceID), including switch display, cursor, backlight, and writing two lines of text. The specific index offset can be found on page 31 of the manual.

CX1100-0002 (with K-Bus)

Features: The top spring terminal (24 V/0 V) supplies power to the system and K-Bus. PE power contacts cannot be used for other potentials.

I/O indicator light:

I/O RUN (green): K-Bus communication is normal.

I/O ERR (red): Flashing indicates an error. The flashing mode consists of "fast flashing start → slow sequence (error code) → slow sequence (parameter)".

Common K-Bus error codes:

Continuous flashing: EMC issue (check for power spikes, grounding).

Pulse parameter 0/1: EEPROM checksum error or code buffer overflow - restore factory settings or reduce the number of bus terminals.

2 pulse parameters 2/0: Unknown data type - update power firmware or check configuration.

3 pulse parameter n (n>0): Bus terminal n table entry error - check if the model of terminal n matches.

Pulse parameter 0: K-Bus command error - may not have been inserted into the terminal or the terminal is damaged, use binary method to locate the faulty terminal.

3 pulse parameters 0/n: K-Bus data disconnection - check if the (n+1) th terminal is connected properly and if the KL9010 terminal is connected at the end.

5 pulse parameter n: Communication error with the register of the nth terminal - replace this terminal.

14 pulse parameter n: The format of the nth terminal is incorrect - power on again, if it still occurs, replace it.

15 pulse parameter n: Change in terminal quantity - power on again.

16 pulse parameter n: K-Bus data length change - power on again.

Power off restart: Some errors will not automatically exit the flashing after clearing, and the power contact must be disconnected before powering on.

CX1100-0003 (with K-Bus+IP Link)

Similar to CX1100-0002, but with two additional fiber optic interfaces (IN x03, OUT x04) provided for connecting to Beckhoff expansion boxes (IExxxx). When wiring, the OUT of this module must be connected to the IN of the expansion box, and vice versa.

The width has increased to 58 mm.

Detailed pins and configuration of system interface

CX1000-N001（DVI + USB）

DVI-I socket: 29 pins, capable of transmitting both digital and analog signals simultaneously. The analog RGB signal is located at pins C1~C4 (C1=red, C2=green, C3=blue, C4=row sync). It can be converted to VGA through a passive adapter.

USB：Type A， Compliant with USB 1.1. Pin 1=VBUS (red), 2=D - (white), 3=D+(green), 4=GND (black).

CX1000-N002 (dual RS232)

COM2 and COM3 are both 9-pin male connectors, using only pins 2 (RxD), 3 (TxD), 5 (GND), and COM2's 4 (DTR). The highest baud rate is 115k.

CX1000-N003 (Audio)

Stereo Line In/Out: 3.5mm socket, tip=left channel, first ring=right channel, sleeve=ground.

Mic In: Mono, Tip=Signal, Sleeve=Ground.
