# Beckhoff CX8030

Hardware · `CX8030` · verification: source checked

The CX8030 is a Beckhoff controller (embedded PC) with an integrated PROFIBUS master interface. It is programmed with TwinCAT via an additional Ethernet interface, and K-bus or E-bus terminals can be connected in series, with the connected system detected automatically at start-up. It runs Windows Embedded CE 6 with TwinCAT 2 PLC and provides web visualization and web-based management.

## Study notes

- Bus interface is a 9-pin D-sub socket with shielding; transmission rate up to 12 Mbaud with automatic detection.
- I/O connection is E-bus or K-bus with automatic recognition at start-up; E-bus/K-bus current supply is 2 A.
- Main memory is 64 MB DDR2 RAM (not expandable); flash memory is a microSD card slot with 512 MB card included, optionally expandable.
- Integrated 1-second UPS backed by 1 MB on the microSD card.
- Operating system is Windows Embedded CE 6 with TwinCAT 2 PLC; programming languages per IEC 61131-3.
- Interfaces: 1 x RJ45 10/100 Mbit/s, 1 x USB device behind the front flap, 1 x bus interface.
- Cooling is passive; internal battery-backed clock for time and date, battery exchangeable behind the front flap.
- Max. power consumption E-bus/K-bus is 10 W (5 V/max. 2 A).
- Dimensions (W x H x D) are 64 mm x 100 mm x 73 mm.
- Relative humidity 95% without condensation; vibration/shock resistance per EN 60068-2-6/EN 60068-2-27; EMC immunity/emission per EN 61000-6-2/EN 61000-6-4.
- Product status: regular delivery, not recommended for new projects; recommended alternative is CX8200.
- Extended support for Microsoft Windows Embedded CE 6 has ended, so up-to-date security updates can no longer be provided.
