StackLoom

StackLoom Monitor: live readings on any Windows PC.

Connect analyzers, flow meters and PLCs over Modbus and watch up to 50 parameters live, with limits, history and charts. No server, no cloud account, no browser address: it opens in its own window.

StackLoom Monitor showing six channels - SO2, NOx, SPM, CO, flue gas flow and temperature - all normal, each with a limit bar and a small trend line
The monitor screen with demonstration values.

Every reading, kept

Values are saved every minute and summarised every hour, so you can look back at any channel from the last hour to the last month and print it.

Trends screen with a 24-hour SO2 chart and the latest, average, lowest and highest values
Trends: 1 hour to 30 days, with latest, average, lowest and highest values and gaps marked.

What it connects to

Any instrument that speaks Modbus: gas analyzers, dust monitors, flow meters, temperature transmitters and PLCs.

ChannelsUp to 50, each with name, unit, range, scaling, offset, warning and alarm limits.
ConnectionsModbus RTU over RS-485 (COM port) and Modbus TCP over Ethernet.
Data types16- and 32-bit integers, 32-bit float, 64-bit double, with selectable byte order.
RegistersInput and holding registers. The program only reads; it never writes to an instrument.
ExportCSV that opens straight in Excel, and print or save any trend as PDF.
Runs onWindows 10 and 11 (64-bit). Listens on the PC itself only, so nothing is reachable from the network.

Live data

Three demonstration stations. The readings move every few seconds for illustration only; a real plant's data stays on the PC in the plant.
