Study notes

Two serial interfaces are on a 9-pin D-sub socket: one RS232 and one RS485; they are not bound to a particular protocol.
E-bus or K-bus terminals can be attached as required; the CX8280 automatically recognizes the connected I/O system at startup.
TwinCAT 3 programming is via the bus interface or the additional Ethernet interface; TwinCAT 3 licenses must be ordered separately.
Operating system is Beckhoff RT Linux; control software is TwinCAT 3 runtime (XAR) from TwinCAT 3.1 Build 4026.
The microSD card is not included and requires a minimum capacity of 16 GB; an integrated 1-second UPS uses 1 MB on the microSD card.
Internal capacitor-buffered real-time clock stores time and date for more than 21 days.
Dimensions are 71 mm x 100 mm x 73 mm; cooling is passive.
Current supply for E-bus/K-bus is 2 A; maximum E-bus/K-bus power is 10 W (5 V/max. 2 A).
Maximum power consumption is 4 W, or 7.5 W with UPS loading.
Vibration/shock resistance conforms to EN 60068-2-6/EN 60068-2-27; EMC immunity/emission conforms to EN 61000-6-2/EN 61000-6-4.
Product announcement with estimated market release in the 1st quarter of 2027.
TwinCAT 3 platform level: Economy (20).
