Building Automation – News and Updates

Building Automation – News and Updates

The CX8191 is a control system with a switched Ethernet port. It supports the BACnet protocol. E-bus or K-bus terminals can be attached as required; the CX8191 automatically recognizes the type of I/O system connected during the start-up phase.

The control system is programmed with TwinCAT 3 via the fieldbus interface or the additional Ethernet interface. TwinCAT 3 licenses must be ordered via the TwinCAT 3 price list. The BACnet license is already installed on the device and does not need to be ordered separately.

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.

In conjunction with the EL6861 BACnet-MS/TP terminals, the CX8191 can act as a router to MS/TP networks including support for several MS/TP networks.

Further TwinCAT 3 functions and protocols are available for the CX8191, for example OPC UA, MQTT, Modbus TCP or Modbus RTU. All functions and protocols can be found in the TwinCAT product finder if you set the filter under TwinCAT 3 platform level to P20.

The CX8191 is a virtually universal device that can be used very flexibly, from control tasks through to gateway functions.
