Product Description:

The CX5140-0100 embedded PC is designed for flexible uses within industrial automation settings. You may find its form and functionality practical in harsh environments. At its core the Intel Atom E3815 processor, running at 1.46 GHz with a single core, aims to deliver reliable performance. Moreover, it integrates 2 GB of DDR3L RAM to support its processing tasks, ensuring standard daily tasks. This compact unit is part of the CX Embedded PC Systems built around common industrial PC demands.

Looking at what the CX5140-0100 offers with its interfacing options, you will find it comes complete with 2 x Gbit Ethernet ports which allow for fast networking connections through standard cables and networks. The availability of 4 x USB 2.0 ports makes integration with other equipment so that you can perform basic actions on the PC as needs arise. For display purposes, there is a DVI-D video interface that can output high-definition contents to a screen located wherever convenient to you. Also consider that the inclusion of a K-bus or E-bus interface allows customizable expansion using the Beckhoff I/O Bus, which is configured based on order specifications.

The physical design is a point of balance between weight and durability, coming in at approximately 400 g with a compact size of 64 mm x 100 mm x 92 mm it may fit well with your project through being easily integrated in places there might be space concerns. Its sturdy design is meant to be protected because it attains an IP20 protection class preventing touch with energized parts and to lessen the ingress of regular solids, an important aspect as your works are within factory floors.

Symptom  Likely Cause Recommended Fix
Unit shows no LEDs/power-up response 24 V DC supply absent or fuse blown Verify 24 V feed, polarity & fuse; re-power once correct 
Stops during boot (no OS) CFast card ejected/corrupted; BIOS mis-set Reseat or replace CFast; reload backup; load BIOS defaults 
TC status LED red (PLC in STOP) PLC project error or missing license Open TwinCAT, correct compile/runtime errors, reactivate license, switch PLC to RUN 
Flash-access LED stays on or blinks rapidly CFast nearly full or failing Back up data, fit new industrial-grade CFast, reduce excessive logging
Bus-status LED red / blinking code K-Bus / EtherCAT wiring or terminal fault Read blink code, reseat connectors, replace faulty terminal, cycle power 
Device shuts down or throttles in warm cabinet CPU over-temperature (> 60 °C) Improve airflow, clean vents, maintain ≤ 60 °C ambient per spec (beckhoff.com)
Clock resets; “Battery low” message RTC coin-cell depleted Replace battery behind front flap; reset date/time (beckhoff.com)
No Ethernet link even with cable Bad cable or disabled switch port/NIC Swap cable, check switch lights & port config, verify BIOS NIC enable
Endless reboot loop after power loss Damaged OS image on CFast Restore known-good image; use built-in 1-s UPS to finish writes 
PLC watchdog/jitter faults Excess CPU load from non-RT tasks Profile task load, move heavy services off controller, update TwinCAT

Error Code  What it Means
K-BUS ERR LED – persistent continuous flashing

EMC disturbance on the K-bus supply or wiring (over/undervoltage, noise).

Check 24 V supply integrity and apply EMC counter-measures. 

3 pulses / argument 0 K-bus command error: no Bus Terminal present or a terminal is defective. 
4 pulses / argument 0 K-bus data error: break immediately after the power-supply terminal (e.g., missing end terminal 9010). 
4 pulses / argument n Break after Bus Terminal n – wiring interrupted or next terminal not seated correctly. 
5 pulses / argument n Register-communication fault with Bus Terminal n – replace the indicated terminal. 
6 pulses / argument 0 Error during CX5140 initialization – device hardware failure; replace Embedded PC. 
6 pulses / argument 1 Internal data error; perform a power-cycle (hardware reset). 
6 pulses / argument 8 Internal data error (variant); power-cycle the CX5140 to recover. 
7 pulses / argument 0 Process-image length mismatch between expected and actual K-bus configuration. Verify terminal order and TwinCAT I/O map. 
TC LED steady yellow TwinCAT 3 PLC runtime has crashed or raised a fatal error. Investigate PLC logs and user code.
