CX8091 Embedded PC with BACnet/IP or OPC UA
Product status: regular delivery
The CX8091 is a control system with a switched Ethernet port. It supports either the BACnet or OPC UA protocols.
Simultaneous use is not recommended due to the small memory. K-bus or E-bus terminals can be attached as required; the CX8091 automatically recognizes the type of I/O system connected during the start-up phase. The control system is programmed with TwinCAT 2 via the fieldbus interface or the additional 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.
The TwinCAT OPC UA Server provides the functionality of the OPC Unified Architecture (UA) specification. In addition to data access techniques UA also specifies the data coding and the transport protocols.
