Raspberry PLC CPU-Gateway: Raspberry Pi edge controller with dual Ethernet and dual RS-485

The Raspberry PLC CPU-Gateway is the Raspberry PLC processing module from Industrial Shields without local I/O zones. It has two Ethernet ports, two RS-485 ports, Wi-Fi, Bluetooth LE, USB, a real-time clock and a UPS that shuts Linux down safely on power loss. It runs Debian 64-bit, so it works as an edge controller, Modbus or MQTT gateway or data concentrator programmed in Python, Node-RED or C/C++.

Before you choose the Raspberry PLC CPU-Gateway

How much RAM does it have?

The CORE version has 4 GB of RAM. The FLEX version lets you choose 2, 4 or 8 GB.

How do I program it?

It ships with Debian 64-bit. Connect by SSH to 10.10.10.20 (eth0) and use Python, Node-RED, C/C++ or shell scripts. Industrial Shields libraries give direct access to the inputs and outputs.

Can I add I/O to it?

Yes. Add remote I/O over Modbus RTU with moduleX, or choose a Raspberry PLC model with local I/O such as the 21 or 38R.

What happens on a power failure?

The built-in UPS keeps the Raspberry Pi running long enough to shut Linux down cleanly, so the SD card and your data are not corrupted. The real-time clock keeps the time with its own battery.

Can it do CAN, LoRa or 4G?

Not in the CORE version. The FLEX version adds one expansion board: CAN, LoRa or 4G (LTE-M/NB-IoT or LTE Cat 4).
