See every machine's status without walking the shop floor.
ModbusSudo reads PLCs, VFDs, controllers and analog transmitters over Modbus, 4–20 mA, 0–10 V, digital inputs and pulse counters — and the SensorLoop IoT Platform shows running status, process values and downtime for every machine in one place.
This use case runs on SensorLoop products — no custom development needed.
Everything your team needs to watch
Values are read directly from your meters, sensors and controllers, labelled in plain language and shown with the right units.
Temperature
Furnaces, ovens, reactors, cold rooms, bearings
Pressure
Compressed air, hydraulics, steam and pumps
Level
Tanks, silos and sumps
Machine status
Running, idle, stopped or tripped via digital I/O
Run hours & cycles
Counters for maintenance planning
Speed & frequency
Motor and VFD speed, output frequency, current
Production count
Pulse counters for pieces, strokes or batches
Any Modbus register
PLC tags and controller values mapped by name

Insights & analysis
The platform analyses your data continuously and points out what deserves attention.
- Running vs idle time for each machine and shift
- Most frequent stoppage times and machines
- Energy and process values side by side for the same machine
- Maintenance planned from actual run hours, not calendars
- Early warning from slowly rising temperatures or falling pressures
What connects
ModbusSudo works with the equipment you already have. Typical devices in this use case:
- PLCs and HMIs with Modbus RTU or Modbus TCP
- VFDs and soft starters with RS-485
- Temperature, pressure and level transmitters (4–20 mA / 0–10 V)
- Proximity switches, relays and counters (digital I/O, pulse)
- HART-enabled field instruments
Machine & Process Monitoring: common questions
Will connecting to my PLC disturb the machine?+
No. The gateway only reads values over Modbus. It does not change your PLC program or write to the machine unless that is specifically set up.
My machines have no communication port. Can they still be monitored?+
Yes. Running status can be taken from a relay or contactor, and process values from 4–20 mA or 0–10 V transmitters.
Can I see this on a big screen in the plant?+
Yes. The dashboard has a full-screen mode designed for control-room and shop-floor TVs.
