PLC data monitoring over the protocols you already run

Read Modbus RTU, Modbus TCP, OPC-UA, MQTT and Siemens S7 devices from a gateway on an industrial PC or Raspberry Pi, and get live dashboards and alerts

The problem

The data is in the PLC. Getting it out is the project

Every vendor has its own software, and a mixed floor means a mixed set of tools nobody fully owns.

Mixed-vendor PLCs, drives and meters

Register maps known only to the integrator

Data trapped on a single local PC

No remote access without a security headache

Operators watching live equipment status come online
How it connects

A gateway on your network, reading what is already there

The gateway polls your devices locally and sends readings out over an encrypted outbound connection. No inbound ports, no changes to control logic.

Modbus RTU and TCP

Energy meters, VFDs, PLCs and controllers, with registers described in plain English.

OPC-UA and S7

Modern PLCs and existing OPC servers, including Siemens S7-1200 and S7-1500.

MQTT

Devices and edge gateways that already publish, with per-device keys.

What changes

One platform for every device on the floor

Every vendor and every protocol in one place, with alerts, dashboards and history.

  • No proprietary hardware
  • Outbound-only, encrypted connection
  • Old and new equipment side by side
  • Your control logic untouched
Questions

Modbus and OPC-UA monitoring software, answered.

Modbus RTU, Modbus TCP, OPC-UA, MQTT and Siemens S7. Devices that speak none of these can usually be reached through a protocol converter or an existing PLC.

An ordinary industrial PC, a Raspberry Pi or a supported edge gateway such as Advantech or Teltonika, on the same network as the devices.

No. The gateway makes an encrypted outbound connection. Nothing needs an inbound port, and it reads values without changing them.
