BECKHOFF CX1000 Industrial Control PC Complete Manual

RS485 no echo, terminal resistance (default): Switch 1=off (echo on? The actual manual indicates confirmation: off=echo on? Clarification is required). According to pages 24-25 of the manual, there are four typical configurations:

No echo, terminal matching (endpoints): DIP 1=off, 2=on, 3=on, 4=off, 5=on, 6=off, 7=on, 8=on

There is echo, terminal matching: 1=on, 2=off, 3=on, 4=off, 5=off, 6=on, 7=on, 8=on

No echo, no terminal (Drop Point): 1=off, 2=on, 3=on, 4=off, 5=off, 6=on, 7=off, 8=off

There is echo, no terminal: 1=on, 2=off, 3=on, 4=off, 5=off, 6=on, 7=off, 8=off

RS422 full duplex endpoints: 1=on, 2=off, 3=off, 4=on, 5=off, 6=on, 7=on, 8=on

Compact Flash Card and Data Persistence

CF card is the main non-volatile storage medium of the system, and it is recommended to only use industrial grade CF cards supplied by Beckhoff (wide temperature up to+85 ℃, high read and write life). The order number includes CX1900-0015（128 MB）、0017（256 MB）、0021（512 MB）、0023（1 GB）、0025（2 GB）、0027（4 GB）。 The CF slot has an ejection mechanism: press down on the ejection rod with a screwdriver, the card will pop out by about 4 mm, and then it can be manually pulled out. When inserting, make sure that the card is about 1 mm lower than the front panel of the housing.

Note: This slot is a memory interface, not an I/O type CF slot. Replacing the CF card must be done in the event of a power outage, otherwise it may cause the system to crash.

Status LED diagnosis

CPU base module LED

Meaning of LED color

PWR green power supply is normal (powered through PC104 bus)

Link Green Network Link (10 or 100 Mbit)

When the green network speed is 100 Mbit, it lights up

Flashing when sending and receiving green network packets in HDD Act

Flashing when HDD green accesses CF card

Power module LED

PWR: green=normal power supply; Red=short circuit (applicable to CX1100-0001/2/3)

I/O RUN (CX1100-0002/3 only): Green=K-Bus communication is normal

I/O ERR (CX1100-0002/3 only): Red=K-Bus error (flashing code as above)

Programming interface for LCD display screen

The LCD of the CX1100 power module can be controlled through ADS (Automation Device Specification). The Device ID is: CX1100-0001=1, CX1100-0002=2, CX1100-0003=3. The ADS port number is 0x000005000+DeviceID. Common index offset (16 bits):

Offset operation instructions

0xFFF90FF Write cursor off

0xFFF91FF Write cursor enabled

0xFFF92FF Write cursor flashing off

0xFFF93FF Writing cursor flashing on

0xFFF94FF Write Display Off

0xFFF95FF write display enabled

0xFFF96FF write backlight off

0xFFF97FF write backlight on

0xFFFA0FF Write Text Line 1 (16 characters)

0xFFF00FF Write Text Line 2 (16 characters)

The action can be triggered by writing any value to these offsets (such as writing 0xFFFFA0FF with string data attached). Users can display system status, alarm information, etc. in real-time in the application.

Common troubleshooting table

Possible causes and solutions for the fault phenomenon

After powering on, there is no response at all. Check the 24V power supply, fuses, and plug pins (1=+24V, 2=0V) for missing power or wiring errors. The measured voltage must be within the range of 20.4~28.8 V.

The red power supply of the PWR LED is short circuited and all loads are disconnected. Check whether the peripheral devices or bus terminals are short circuited one by one.

CPU module PWR does not light up. PC104 bus power interruption check if the power module is tightly connected to the CPU module without any gap.

Unable to start (not boot) CF card damaged or boot configuration error, replace Beckhoff original CF card; Check BIOS settings (if any); Attempt to restore the factory image.

Network connection failure cable, hub or IP configuration error check RJ45 pin (1=TD+, 2=TD -, 3=RD+, 6=RD -); Attention should be paid when using a crossover line to directly connect to a PC.

DVI has no display distance that is too long, resolution that is too high, reduced resolution, or cable that is shortened to within 5 meters; Test the analog output using a DVI to VGA adapter.

USB devices do not recognize USB 1.1 compatibility issues and only support low-speed and full speed devices (up to 12 Mbit/s).

Touch screen signal cannot be read. Connect the touch screen to the wrong port. Ensure that the touch screen USB cable is connected to the USB port of the CPU module (not the USB port of the system interface)? The actual USB of N001 is an expansion port.

K-Bus I/O ERR flashes 3 times pulse n terminal n configuration error or disconnection check whether the actual terminal model is consistent with TwinCAT configuration; Check if terminal n+1 is securely plugged in; Confirm that there is a KL9010 terminal at the end.

K-Bus I/O ERR continuous flashing EMC interference check grounding and power filter; Separate the communication line from the power line for wiring.

System time loss, internal battery depletion, battery replacement (requires disassembly, executed by Beckhoff service).

Retirement and disposal

Software shutdown: Normal shutdown of the operating system (if running Windows XPE or CE).

Power outage: Cut off the 24V power supply.

Disassembly: Remove the entire module assembly from the DIN rail according to the previous disassembly steps, and use a separation groove tool to separate each module.
