Installation, wiring, and start stop operation

5.1 Mechanical Installation

Installation requirements: Only allow horizontal installation on TS35 standard DIN rails; A 30mm ventilation gap should be reserved above and below the equipment, with a working environment temperature of -25~60 ℃.

Guide rail fixation: Pull the bottom buckle into the guide rail and reset it after installation; Vibration scenes require additional reinforcement.

Memory card replacement: CFast and microSD cards are both press to eject and must be powered off. Only use Beifu industrial grade memory cards to avoid data damage.

EtherCAT terminal installation: Passive EtherCAT terminals should not be directly attached to the power terminal to avoid abnormal bus signals.

5.2 Power Wiring

Power supply specifications: standard 24V DC (fluctuation -15%/+20%), maximum power consumption of the whole machine is 16-18W, and full load charging can reach 34W.

Terminal partition

Us terminal: Provides power to embedded PC+bus, requires 4A fuse (UL standard) or NEC Class2 power supply;

Up terminal: Provides power to external terminals/sensors, maximum 10A, equipped with 10A slow melting fuse.

Wiring specifications: The cable diameter is 0.5~2.5mm ², and the stripping length is 8~9mm; it is forbidden to only disconnect 0V, and the 24V positive pole must be disconnected.

UL compliance: Cannot connect to infinite current power supply, strictly follow UL label requirements.

5.3 Start stop operation

Power on: After confirming that the module, wiring, and installation are correct, connect 24V and the device will automatically start and load the system.

Power off: Standard procedure: Close all programs → Normal shutdown → Cut off 24V power supply; Prohibit direct power outage during operation to prevent data damage to the storage card.

System configuration

6.1 Beckhoff Device Manager

Remote device configuration through browser, default account Administrator, password 1; The new version uses HTTPS (port 443), while the old version uses HTTP (port 80), requiring the same network segment and firewall port to be released.

6.2 TPM Security Module

Onboard fTPM 2.0, used for data encryption and tamper proof; It needs to be enabled in BIOS (with security devices enabled in UEFI mode) and is only compatible with Windows 10 1809 and above 64 bit systems.

6.3 Windows Network Configuration

Network port recognition: The two network ports in Device Manager are named TwinCAT Intel Gigabit Network Card # 1/# 2.

Jumbo Frames: Requires installation of the original Intel network card driver (which will uninstall the Beifu real-time driver), supporting 4088/9014 byte jumbo frames.

NIC Teaming: The original driver is also required, and network card redundancy and fault switching can be configured.

Real time driver recovery: Use TcRteinstall.exe to reinstall the real-time driver of Beifu Ethernet and restore the real-time performance of TwinCAT.

6.4 TwinCAT 3 configuration

Engineering view: Distinguish between E-Bus (EtherCAT) and K-Bus (bus terminal) topologies, and the tree view automatically identifies couplers and terminals.

Device search and scanning: Search for target devices within the same network segment using IP/hostname, automatically identify I/O and bus modules through scanning, and complete project mounting.

EtherCAT cable redundancy: Using dual network ports to build a ring network, single line disconnection does not affect communication, and the redundancy function is enabled in TwinCAT advanced settings.

Hardware watchdog: Call the FB-PcWatchdog-BAPI function block to automatically restart the device when the PLC freezes/loops. It is recommended to shut it down during debugging.

1-second UPS function

Principle: Built in supercapacitor, provides short-term power supply after power failure, stores up to 1MB of persistent data, and protects PLC data from loss during power failure; Not supplying power to the peripheral bus.

configuration process

BIOS enables UPS function, sets delay and power supply parameters;

Configure Windows Unified Write Filter (UWF) and add a read-write exception directory;

Declare the VAR PERSISTENT persistent variable in the PLC and call the FB_S-UPS_SAPI function block.

Working mode: supports four modes: “data storage+quick shutdown”, “data only”, “direct shutdown”, and “status detection only”; The data is saved by default in the Port_85x.bootdata file on the CFast card.

Status monitoring: View data loading and system operation status through the PlcAppSystemInfo structure.

Fault diagnosis

8.1 Status LED indicator light

Indicator light status description

PWR evergreen=normal power supply; Red/yellow short light during startup phase

TC green=TwinCAT running, red=stop, yellow=PLC fault/crash

HDD red/flashing=read/write CFast card

FB1/FB2 fieldbus status indicator light

8.2 Bus Diagnosis

K-Bus

Hardware LED: K-BUS RUN green=normal, K-BUS ERR red flashing=fault; Using “flash+two-stage slow flash” encoding to distinguish fault codes and fault terminal positions;

Software diagnosis: Read the State variable in TwinCAT, identify bus errors, configuration changes, watchdog issues, etc. through bit definitions, and reset the bus through function blocks.

E-Bus (EtherCAT): L/A light off=not connected, constantly on=no data connected, flashing=normal communication.

Common faults and solutions: The whole machine has no response. Check the power supply/fuse; Unable to start checking storage card BIOS； Controller abnormality troubleshooting software and external devices.
