"The EasyE4 is a completely new development," says Sascha Lindemann. The responsible product manager at Eaton Industries adds: "The small controller not only has many new functionalities on board, but is also equipped with a new version 7 of the easySoft programming software." The focus of the new development was on improved performance, a larger memory, the integration of Ethernet as a communication protocol, the greatest possible expandability and compatibility with the previous series.

How much has the programming software changed with the update? "We have retained the familiar and proven programming concept of the previous versions and also expanded it," says Lindemann. The user can choose between four programming languages: the circuit diagram can be created using function blocks, ladder diagrams, Eaton's own Easy programming or structured text (ST). Version 7 provides additional function blocks in EasySoft, such as data logging, min/max, alarm module, three-point controller or an e-mail alarm. "This significantly expands the range of applications for Easy," says Lindemann with conviction. Users can also create their own function blocks. Existing programs from existing Easy devices can still be used with EasySoft 7.

The basic EasyE4 device can be expanded to a maximum of 188 I/Os using up to eleven expansion modules. AC, DC, UC devices, analog and digital extensions can be combined as required in mixed operation. The expansion modules are connected via the new 'EasyConnector' connector on the front, which significantly simplifies installation and removal. With a total of fourteen versions of base unit and expansion modules, the number of variants has been greatly reduced compared to the previous series, while at the same time the range of applications has been expanded. With the micro SD card in the base unit, individual application options can also be implemented, such as the definition of start programs, individualization of the control relay or the display of company-specific graphics.

The EasyE4 can be connected to all standard LAN/WLAN routers, repeaters or dLans via the integrated Ethernet interface and can therefore also be networked with the IIoT. Information from the control relay can thus be displayed on websites or used for visualization with the integrated Easy web server. The user can design their own dashboard and access the EasyE4 using a smartphone, tablet or notebook. Up to 80 EasyE4 devices can also communicate in a shared network via the Ethernet interface and with the integrated NET network function.

"SmartWire-DT is currently not supported in the first expansion stage of the EasyE4. However, we are planning to develop communication modules over the course of the product cycle. SmartWire-DT is also planned as part of this," says Lindemann.
