BECKHOFF C6030 Industrial Control Computer

3.2 Installation method

The C6030 comes with a standard mounting plate (Standard Type 1) when it leaves the factory, which is used to install it inside the control cabinet through the narrow edge (side) of the equipment. Optional mounting plate 2 (order numbers C9900-M668, C9900-M669) can be installed only through the right side wall. The installation board is fixed with 4 Torx TX10 screws, with a tightening torque of approximately 0.5 Nm.

Installation direction (using standard installation board 1):

Installation through the back wall of the device

Install through the top surface of the device

Install through the bottom of the device

When using optional mounting board 2, the interface can be oriented in any direction (up, down, left, right).

3.3 Installation precautions

Ventilation gap: At least 5 cm of free space must be left around the equipment to ensure air circulation.

Protection level: IP20 (finger protection only, no waterproof). Do not use in damp, dusty, or explosive environments.

Fixed: Use M4 screws to hang the keyhole of the mounting plate into the pre installed screws, and then tighten them.

Grounding and electrical connection

4.1 Protective Grounding and Functional Grounding

The C6030 body is equipped with a protective grounding terminal (PE), which must be connected to the central grounding point of the control cabinet using a wire or flat conductor with a cross-sectional area of not less than 4 mm ².

Protective grounding (PE): prevents dangerous contact voltage and complies with the requirements of EN 60204-1:2006 for PELV circuits.

Functional grounding (FE): Ensure electromagnetic compatibility (EMC) and equipment meets EN 61000-6-2 (immunity) and EN 61000-6-4 (radiation). Failure to perform functional grounding may result in damage caused by electromagnetic interference.

4.2 Power wiring sequence

Complete the protective grounding connection first.

Connect all data cables (Ethernet, USB, DisplayPort).

Connect the 24V power cord to the power plug, then insert the plug into X101 and lock it.

Finally, connect the 24V power supply.

Full analysis of status LED indicator lights

The front panel of C6030 provides four status LEDs, which are crucial for on-site fault diagnosis.

Meaning of LED color/status

UPS OCT is constantly off and not connected to UPS OCT

Blue flashing Bootloader activation

Yellow constant light, medium signal quality

Green constantly on, good signal quality

Red constant brightness, poor signal quality

PWR is constantly off and PC is turned off

White constantly on VCC power supply fault

Crimson constant light SUSV activation (if present)

The yellow light is constantly on. Windows has been shut down, but the power is still on

Green constantly on and running normally

Red constant on reset/power failure

Green/yellow flashing Bootloader running normally

Red/yellow flashing Bootloader startup sequence

Crimson flashing (0.5s) SUSV capacitor test

Red/magenta flashing I2C transmission checksum error

Blue flashing (2s) requires contacting Beckhoff service

HDD red flashing storage media activity (note: NVMe SSD activity will not light up this LED)

TC green constant light TwinCAT operation mode

Blue constant brightness TwinCAT configuration mode

Red constantly on TwinCAT stops

TwinCAT, which is constantly extinguishing, has not been activated

UPS OCT Technology and Configuration

UPS OCT (One Cable Technology) is Beckhoff's unique uninterruptible power supply communication technology, which modulates 24V power supply and bidirectional data on the same pair of lines, allowing external UPS (such as CU81xx series) to be connected with just one cable. C6030 supports this function (can be confirmed through the nameplate).

BIOS configuration steps:

Start up and enter BIOS Setup, then go to the Advanced tab.

Enter the Power Controller Options.

Change UPS OCT Access from default [Off] to [Auto].

Save and exit.

After activation, the BIOS will display the detected UPS and connection method (detected via OCT or detected via USB). If both USB and OCT are connected at the same time, the priority of USB connection is higher.

If you need to enable UPS OCT from the factory, you can order the special BIOS option C9900-B654.

Maintenance and replacement of vulnerable parts

Beckhoff recommends regularly replacing the following components to ensure long-term reliability of the equipment:

Suggested replacement cycle for components

UPS battery pack for 5 years

2.5-inch hard drive for 5 years or 20000 hours (>40 ℃)/30000 hours (<40 ℃)

3.5-inch hard drive for 5 years

Fan for 7 years

CFast/SSD/MicroSD/CF 10 years

Motherboard battery (CR2032) 5 years

7.1 Replacing the motherboard battery

The C6030 uses a CR2032 lithium battery (3V, 225mAh) to maintain real-time clock and BIOS settings. When replacing:

Remove the 4 Torx TX10 screws from the right cover plate.

Find the battery holder (located next to the SSD).

Use a lever to pry up the old battery from the negative side and remove it.

Install a new battery with the positive pole (+) facing upwards, insert it diagonally under the positive pole contact, and then press it down.

Attention: Only R/C (BBCV2) type, model RC2032, can be used. Other types are not allowed to avoid fire or explosion.
