P.L.C

Q: How does P.L.C compare to Siemens / Allen-Bradley, Ignition SCADA or Node-RED DIY on cost and capability?

vs Siemens / Allen-Bradley: PLC behaviour on ESP32/NodeMCU at commodity-silicon cost — proven controlling live SCADA water-treatment plants. vs Ignition SCADA: Control logic wired to the operational ledger — process events become inventory and alerts. vs Node-RED DIY: Signed OTA firmware, autonomous control loops and fleet dashboards — industrial, not hobbyist.

Programmable logic control on ESP32, NodeMCU and Raspberry Pi.

Industrial edge control on commodity silicon — the same ESP32/NodeMCU architecture that runs India's zero-chemical SCADA water-treatment plants.
GPIO, relays and sensors wired straight into the ledger.
PLC behaviour without PLC pricing.

What you get

Capabilities that ship on day one.

Commodity-silicon PLCs

ESP32, NodeMCU and Raspberry Pi run hardened control logic — no proprietary controller required.

Sensor to ledger telemetry

GPIO inputs, ADC readings and sensor data land as ledger events automatically.

Relay & actuator control

Outputs drive relays, solenoids and actuators on rules you configure.

Autonomous offline loops

Control loops run on-device — the plant works even fully disconnected.

OTA firmware management

Firmware rolls out signed and staged — a fleet of controllers updates as one.

Both options are open: you can add the Industrial IoT Suite (+₹4,999/site/mo · $69) onto Growth (₹2,999/site/mo), or choose Scale at ₹7,999/site/mo billed yearly (₹9,999/mo monthly · $109/mo · or ₹2,49,999 One-Time Perpetual). Scale includes the full 6-app AI Engine Suite, the 5-app Manufacturing & B2B Suite, and any 1 Industry Vertical Suite free (with extra Vertical Suites at 40% off) — so as soon as you pair a vertical suite with AI or BOM, Scale costs less per site. Every plan includes unlimited staff and registers, plus −10% at 10+ sites and −20% at 25+ sites.

Yes. On cloud plans, P.L.C runs inside your dedicated TolsTek Isolated Cloud container (isolated database and Redis cache per tenant, with zero backend source code on counter devices). For hospitals, plants, defence and sovereign enterprises, Scale Perpetual and Enterprise deploy on locked Tier 1–4 Server-Rack hardware or fully air-gapped local networks — so patient records, plant telemetry, cryptographic keys and ledger rows never leave your perimeter.

There is no API glue, webhook chain or CSV sync to maintain. P.L.C shares the exact same live stock, customer and fiscal ledger row as IoT Stock, Manufacturer and AI Control Center — switching them on simply exposes new workflows over the data your sites are already generating.

Minutes, not weeks. Standard thermal & label printers (Epson, TSC, Zebra, Brother), weight scales, EMV payment terminals, ESP32/Modbus controllers and LoRaWAN nodes bind through auto-discovery over LAN, WebUSB or CloudPRNT — with zero per-workstation driver babysitting or SCADA consultancy bills.
