A CM4 industrial edge gateway and an isolated STM32H743 I/O board — IEC 61131-3, DIN-rail, -20 to +85°C, at a quarter of Siemens ET200 cost.
Every connected factory needs rugged hardware at the edge — a gateway to run logic and talk protocols, and I/O to touch the real world. A Siemens ET200 node lands around ₹85K before you have even started. PARAM-GW1 is a Raspberry Pi CM4-based industrial gateway (₹35K) with real on-board edge compute, and PARAM-PLC is an STM32H743 isolated I/O board (₹22K). Both are IEC 61131-3 programmable, DIN-rail mountable and rated -20 to +85°C for real Indian shop-floor conditions. They speak Modbus, OPC-UA and MQTT Sparkplug B natively, so they drop straight into a PARAM-CONNECT deployment — genuine industrial capability at a quarter of the incumbent price.
