Beckhoff CX8190

The CX8190 is a fanless embedded controller running Windows Embedded Compact 7 with the TwinCAT 3 runtime. It has an Arm Cortex-A9 processor and provides one RJ45 10/100 Mbit/s Ethernet interface plus a bus interface switched to two RJ45 sockets. K-bus or E-bus terminals connect to it and the connected I/O type is recognised automatically at start-up.

Study notes

Product status: regular delivery, not recommended for new projects; recommended alternative is CX8290.
Control software is TwinCAT 3 runtime (XAR); TwinCAT 3 licenses are ordered via the TwinCAT 3 price list, and TwinCAT is supported only up to build 4024.
TwinCAT 3 platform level: Economy (20).
Main memory is 512 MB DDR3 RAM (not expandable); flash storage is a microSD slot with a 512 MB card included, optionally expandable.
An integrated 1-second UPS (1 MB on microSD card) is provided.
Interfaces: 1 x RJ45 10/100 Mbit/s and 1 x bus interface; the bus interface is 2 x RJ45 switched at 100 Mbit/s, so three RJ45 sockets in total.
Supported protocols include real-time Ethernet, ADS UDP/TCP and EAP (EtherCAT Automation Protocol), plus OPC UA, MQTT, Modbus TCP and Modbus RTU.
I/O connection is E-bus or K-bus with automatic recognition at start-up.
Dimensions (W x H x D) are 71 mm x 100 mm x 73 mm.
Current supply to E-bus/K-bus is 2 A; max power consumption of E-bus/K-bus is 10 W (5 V, max 2 A).
Max power consumption is 4 W, and 9 W when loading the UPS.
Cooling is passive; diagnostics LEDs are 1 x TC status, 1 x WD and 1 x error; an internal battery-backed clock keeps time and date, with the battery exchangeable behind the front flap.

Safety

Protection rating IP20.
Operating temperature range -25 to +60 °C; storage temperature range -40 to +85 °C.
Relative humidity 95%, no condensation.
Vibration/shock resistance conforms to EN 60068-2-6/EN 60068-2-27.
EMC immunity/emission conforms to EN 61000-6-2/EN 61000-6-4.
Approvals/markings: CE, UL.
Power supply is 24 V DC (-15%/+20%).
Extended support for the installed operating system (Microsoft Windows Embedded Compact 7) has ended, so up-to-date security updates can no longer be provided.
