128 MB RAM for runtime and process data

4 KB I/O DPRAM buffer between CPU and K-Bus terminals

2 A K-Bus terminal power for connected I/O slices

Material Composition:​

Housing: industrial molded plastic embedded PC case

Heat sink where required: aluminum passive cooling element

PCB: multilayer FR4 industrial board

K-Bus and Ethernet connectors: insulated housings with metal contacts

Structural Characteristics:​

Compact DIN-rail mountable CX CPU module

Front diagnostic LEDs for power, LAN, K-Bus and flash access

RJ45 Ethernet ports on the module front or system face

PC/104 or internal system bus stacking according to CX9000 configuration

No DVI/USB in the 1001 configuration; visualization is handled via Ethernet HMI

Working Principle:​

The controller boots Windows CE and TwinCAT from internal flash, loads the PLC project into RAM, scans K-Bus terminals through the I/O DPRAM, executes control logic, writes outputs and exchanges data over Ethernet. NOVRAM stores retained variables across power cycles, while the battery-backed clock provides timestamps.

Installation Requirements:​

Mount on a 35 mm DIN rail or in a CX system carrier inside an IP20 cabinet

Supply 24 V DC with appropriate fusing and proper earth grounding

Connect K-Bus Bus Terminals in the supported chain order

Reserve ventilation space and avoid enclosed non-ventilated compartments

Usage Precautions:​

Do not install DVI/USB peripherals not supported by the 1001 variant

Backup the TwinCAT project and flash image before firmware changes

Avoid electrostatic contact with K-Bus connectors and terminal rows

Keep ambient temperature within 0 °C to +55 °C and humidity below 95% condensing
