Ethernet I/O: BusWorks® NT Series
NT2000 Series: Ethernet I/O Modules with OPC UA and MQTT
BusWorks® NT2000 Ethernet I/O modules with OPC UA and MQTT support offer a cost-effective solution for Internet of Things (IoT) applications. NTE models with dual RJ45 ports provide the protocol interface, IoT functionality, plus I/O signal processing channels. NTX expansion modules can plug in to add extra I/O channels or a mix of signal types over a single Ethernet interface.
The NT Ethernet I/O module provides an OPC UA server and MQTT client in addition to the fieldbus protocol stacks (Modbus TCP/IP, Ethernet/ IP, and PROFINET). The integrated IoT functionality offers a standardized data exchange to simplify industrial communication in an increasingly complex environment.
Select from a variety of models providing analog or discrete I/O signal processing channels. Applications include monitoring temperature, level, flow, pressure, and other sensor types or controlling relays, motors, and other switching equipment.
OPC UA represents I/O data from field devices as objects in an address space for easy access from the cloud and other system clients without protocol gateways. The NTE module operates as an OPC UA server giving more users access to current data for decision making and process optimization.
The MQTT client uses a publish/subscribe model to share data through a message broker which requires less overhead and less bandwidth to communicate.
Key Features & Benefits
- Connect field devices to the cloud with expandable I/O capacity enabling up to 64 I/O channels of mixed signal types on one IP address
- OPC UA and MQTT protocol support make data available for sophisticated applications in the cloud or on edge gateways
- Combine Ethernet protocols with IoT protocols for real time and IoT data transfer over the same network cable
- Field-selectable Modbus/TCP, EtherNet/IP, or PROFINET protocols
- EtherNet/IP and PROFINET are operated in parallel to the IoT protocols with highest priority to assure short cycle times
- Enable asset management, condition monitoring, diagnostics, visualization, predictive maintenance, extended configuration, and parameterization
- Easy to use GUI for OPC UA information model design
- No hassle with protocol details. Abstract data object model lets the user application simply read and write data that is transparently fed into the IoT protocols and information models
