#Supported Hardware
Edge Hub is designed to run on rugged, DIN-rail industrial gateways at the edge of the machine — close to the PLC and the field bus, with no fans and a wide operating-temperature range. The reference platform is the Siemens SIMATIC IOT2050 Advanced.
#SIMATIC IOT2050 Advanced
An open, Arm-based industrial IoT gateway. Dual Gigabit Ethernet lets Edge Hub sit between the plant network and the machine network, while the RS-232/422/485 COM port and the field-bus connection feed the PLC and IO-Link data that the rules engine evaluates.

The
-0BA00-order number is the Advanced model. A hardware-compatible variant with an on-board M.2 slot (for SSD or 5G/Wi-Fi/BT modules) is sold separately as6ES7647-0BB00-1YA2.
#Why this platform
- Fanless and rated for the cabinet. 0–50 °C, DIN-rail mount, 24 V DC — it installs next to the PLC, not in a server room.
- Two isolated Ethernet ports. Keep the plant/OT network and the machine network separate while Edge Hub bridges data between them.
- Enough compute for continuous recording and rule evaluation. The quad-core A53 handles PLC frame decoding, IO-Link polling, and the rules engine hot path with headroom to spare.
- Standard Linux. Edge Hub ships as a normal Linux service — no proprietary runtime — so it deploys and updates like any other container/systemd workload.
Other Arm64 or x86-64 Linux gateways with two Ethernet ports and a field-bus connection can run Edge Hub as well; the IOT2050 Advanced is simply the validated reference.
