BECKHOFF CX52x0 Industrial Control Computer Maintenance Guide

Save and exit. If you need to reset the TPM key after activation, you can find the corresponding option in the BIOS.

4.3 Restoring Beckhoff Real Time Drive

When enabling Jumbo Packet or NIC Teaming, it may be necessary to install Intel raw drivers, which will override Beckhoff's real-time drivers. Afterwards, EtherCAT communication may be affected (real-time performance may decrease or scanning may not be possible).

Recovery method:

Find TcRteinstall.exe (TwinCAT 2 is located at C: TwinCAT 10 , TwinCAT 3 is located at C: TwinCAT 3.1 System ).

Run as an administrator and select the Ethernet interface that requires real-time driver installation (usually corresponding to the port used by TwinCAT).

Click 'Install' to restart the device. Before rescanning I/O devices in TwinCAT, ensure that the interface is bound to a Beckhoff driver.

4.4 Scanning CX52x0 and configuring EtherCAT redundancy in TwinCAT

Scanning devices: In the TwinCAT project, right-click on I/O Devices and select Scan. The system will automatically detect CX52x0 and the K-bus or E-bus modules mounted behind it.

EtherCAT cable redundancy: The CX52x0's two independent Gigabit Ethernet ports can achieve EtherCAT ring network redundancy.

Configuration: Double click EtherCAT Master in TwinCAT to enter the EtherCAT tab>Advanced Settings>Redundancy. Check the Second Adapter and search for the corresponding physical network port.

Effect: When there is a disconnection in a certain part of the ring network (such as between EK1100 and EK1110), the State column will display LINK_MIS A or LINK_MIS B, but communication will not be interrupted, and the slave station after the fault point is still controllable.

Safety operation standards and maintenance cycle

To ensure the long-term reliability of CX52x0 in harsh industrial environments, please follow the following recommendations:

Component replacement cycle suggestion note

The precursor of a 5-year callback or BIOS loss for the motherboard battery (CR2032).

CFast/microSD cards have a write life of 10 years based on NAND flash memory, and SLC or high durability industrial cards should be selected for frequent data recording.

Pay attention to the VBUS LED on the power terminal with the device. If it frequently displays overload, check whether the external sensor/actuator is short circuited.

Cleaning depends on the environment. After turning off the power, use a soft damp cloth to clean the casing. It is strictly prohibited to use compressed air (which may blow dust into the interior and cause a short circuit). The ventilation opening must be kept unobstructed.
