Description
CX7291 Beckhoff Embedded PC with Arm Cortex-A9, BACnet/IP and integrated I/Os Arm Cortex-A9, 720 MHz TwinCAT 3 runtime (XAR) from TwinCAT 3.1 Build 4026 (XAE) Ethernet, BACnet
The CX7291 Embedded PC has an Arm Cortex-A9 single-core processor with 720 MHz.
In the basic configuration, the CX7291 has a slot for a microSD card and an Ethernet interface. As a special feature, the CX7000 series has eight integrated multi-functional inputs as well as four integrated multi-functional outputs.
E-bus or K-bus terminals can be attached as required; the CX7291 automatically recognizes the type of I/O system connected during the start-up phase. The control system is programmed with TwinCAT 3 via the Ethernet interface.
BACnet (Building Automation Control Network) is a standardized, manufacturer-independent communication protocol for building automation. Areas of application include HVAC, lighting control, safety and fire alarm technology.
