Being marketed as an IIoT device differentiates it from classical "mission critical/rock solid" PLC modules I guess. Treat it as an Arduino with WiF and Ethernet but with friendly screw terminals and connectors instead of needing a shield for interfacing te traditional sensors and actuators. And with an woefully overpowered microcontroller.
