Bi-Directional Gateway

With the Service Pack 2, HMS Networks extends the functionality of the Ixxat CAN@net NT and CANbridge NT series. Users can now add smart, event-controlled network actions and versatile bi-directional MQTT-messaging to cloud applications. The new hardware CAN@net NT 100 complements the CAN@net NT range with new network connectivity. The Ixxat CAN@net NT and CANbridge NT product families enable smart and seamless CAN-based networking on-site and remotely. The CANbridge NT enables easy coupling of up to four CAN and CAN-FD networks using filter and translation rules. Network wiring can be simplified through tree and star topologies, and all connected segments are protected thanks to electrically isolated bus interfaces. All CAN@net NT products come with an additional Ethernet interface, allowing very distributed networks by coupling up to four CAN@net NT devices using Ethernet. CAN@net NT products also allow remote access to CAN and CAN-FD networks via Ethernet and PC.

The Service Pack 2 introduces enhanced "Action Rules" programming for flexible definition and execution of events and actions for all CAN@net NT and CANbridge products. Based on LUA script processing, these user-defined actions can be triggered upon e.g. pre-defined message content or status information. The Ethernet interface of the CAN@net NT series enables direct cloud connectivity via the implemented MQTT protocol. In SP2, bi-directional MQTT messaging is introduced. In addition to transmitting e.g. alarms and status information to mobile devices, messages can now also be received from the cloud for LUA script-based pre-processing, plausibility checking and transmission to the CAN bus.
