The easyE4 delivers secure, flexible connectivity across machine building, building automation, and IoT environments. With support for Ethernet, Modbus TCP/RTU, easyNET, MQTT, and JSON API, it integrates effortlessly into local systems as well as cloud platforms such as Amazon Web Services (AWS) and other cloud services.
Remote I/O via easyNET enables distributed control without additional programming, while MQTT connectivity ensures fast, secure, and scalable data exchange with cloud and IoT platforms. Thanks to encrypted communications, broad protocol compatibility, and cloud readiness, the easyE4 provides reliable, future‑ready networking—whether in machines, technical installations, smart buildings, or connected IoT architectures.
The easyE4 features an integrated Ethernet interface with an RJ45 connector. This high-performance interface is not only compatible with various communication protocols, but is also encrypted using our own easyE4 certificates for protection against cyber-attacks. The various communication options are described below.
The integrated NET network function enables several easyE4 devices in the same network to communicate with each other via Ethernet. If multiple easyE4 devices are included in a project, the easySoft software will automatically configure the NET connection allowing data to be exchanged smoothly between them. The data of an easyE4 device can also be temporarily stored on a NET marker and displayed on another device
