Product overview
The CX7000 Embedded PC has an ARM Cortex™ M7 single-core processor running at 480 MHz and the following basic configuration:
- a microSD card slot with integrated 512 MB microSD card,
- an Ethernet interface (10/100 Mbit/s, RJ45),
- a USB interface (max. 12 Mbit/s, max. 100 mA),
- integrated multi-function I/Os.
The CX7000 is programmed with TwinCAT 3 via the Ethernet interface. In addition, the Beckhoff Device Manger is available as a web interface for configuring the CX7000.
Multi-function I/Os
Special features of the CX7000 series are the eight integrated multifunction inputs and four integrated multifunction outputs.
- 8 digital inputs, 24 V DC, filter 3 ms, type 3, 1-wire technique
- 4 digital outputs, 24 V DC, 0.5 A, 1-wire technique
The integrated multifunction I/Os of the CX7000 can be configured via TwinCAT 3 for other operation modes in order to enable fast counting or the processing of analog values:
- Counter mode: 1 x digital counter input 100 kHz, 1 x digital input for up/down counter 20 kHz, 2 x digital counter outputs
- Incremental encoder mode: 2 x digital inputs for 250 kHz encoder signal (A/B input), 2 x digital encoder output
- Analog signal mode: 2 x digital inputs configured as analog inputs 0 to 10 V, 12-bit resolution with 16-bit representation
- PWM signal mode: 2 x digital outputs configured for PWM signal, 15 Hz…100 kHz
Power supply terminal
EtherCAT Terminals (E-bus) or Bus Terminals (K-bus) can optionally be connected directly on the right-hand side; the CX7000 automatically recognizes which system is connected during the start-up phase. If further electrical signals are to be processed, the CX7000 can be extended as required and extremely flexibly by EtherCAT Terminals or Bus Terminals in addition to the integrated I/Os.
Firmware
The real-time operating system TC/RTOS, which is based on FreeRTOS, is used as the operating system or firmware. Note that TC/RTOS is a closed system and you cannot install your own software. This provides a certain level of security, as third-party software such as viruses or similar cannot be installed and the CX7000 can be connected to a network. The CX7000 can be used from TwinCAT 3.1 Build 4024.12. The following TC 3 functions are included and licensed:
- TC1000 TC3 ADS
- TC1100 TC3 IO
- TC1200 TC3 PLC
- TF4100 TC3 Controller Toolbox
- TF4110 TC3 Temperature Controller
