CX8280 | Embedded PC with RS232/RS485
CX8200 Embedded PC series: higher computing power in a compact format
Embedded PCs with an Arm® Cortex® CPU
TwinCAT runtime for Linux® from Beckhoff
The CX8280 Embedded PC has two serial interfaces, one with RS232 and one with RS485 physics. These are both located on the D-sub socket. They are not bound to any particular protocol and can be used with the corresponding TwinCAT 3 Functions for the different serial communication protocols.
The CX8280 features an Arm® Cortex®-A53 dual-core processor with 1.2 GHz. The basic configuration of the CX8200 includes a 1 Gbit Ethernet interface, a USB 3.0 interface, a 1 GB LPDDR4 RAM, and a slot for a microSD card. The microSD card is not included in the scope of delivery and must be ordered separately, taking the desired memory capacity into account.
E-bus or K-bus terminals can be attached as required; the CX8280 automatically recognizes the type of I/O system connected during the start-up phase. The control system is programmed with TwinCAT 3 via the bus interface or the additional Ethernet interface. TwinCAT 3 licenses must be ordered via the TwinCAT 3 price list.
Beckhoff RT Linux® is used as operating system.
