Machine & PLC Connectivity
Connect Siemens, Mitsubishi, Allen-Bradley and legacy controllers through Kepware, OPC UA and MQTT.

PSPTechHub connects machines, PLCs and sensors to PTC ThingWorx and turns live shop-floor data into dashboards, alerts and predictive maintenance — from a pilot line to every plant.
Quick answer
ThingWorx IIoT services connect factory machines, PLCs and sensors to the PTC ThingWorx platform so plants can see live equipment status, get alerts, track energy and predict maintenance. PSPTechHub designs the connectivity, builds the dashboards and supports the solution after go-live.
Definition
ThingWorx IIoT (Industrial Internet of Things) is the use of the PTC ThingWorx platform to collect data from industrial equipment, store it, and show it in real time. Machines and PLCs send data through Kepware, OPC UA or MQTT. ThingWorx models each asset, applies rules and alerts, and serves dashboards to operators, engineers and managers.
PLCs, legacy controllers, sensors and test systems
Live machine status, KPIs and threshold alerts
Trends and asset health that drive maintenance before failure
Architecture
PLCs, sensors, test rigs and legacy controllers on the shop floor
Kepware / KEPServerEX, OPC UA or MQTT gateways
Asset models, rules, alerts and analytics
Time-series database for live and historical data
Web dashboards on desktop, tablet and mobile

Capabilities
Eight building blocks, combined to match your machines, data and goals.

Most requested
Predictive maintenance & energy monitoring
Connect Siemens, Mitsubishi, Allen-Bradley and legacy controllers through Kepware, OPC UA and MQTT.
Color-coded machine status with live speed, efficiency and part counts on every line.
Asset health, criticality scoreboards and trend alerts that flag issues before breakdowns.
Track electricity, gas, steam, water and solar KPIs with weather context and savings targets.
Separate views for operations, engineering and management — OEE, emissions and test results.
Threshold-based alerts plus scheduled PDF and Excel reports for performance and compliance.
Persist high-frequency machine data in InfluxDB or PostgreSQL for history and analysis.
Link IIoT data with SAP and MES so production, maintenance and planning share one picture.
Connectivity
Most plants use more than one. PSPTechHub picks the right mix per machine.
| Option | Best for | How it works |
|---|---|---|
| Kepware (KEPServerEX) | Mixed PLC brands and legacy controllers | 150+ industrial drivers read tags and publish them to ThingWorx |
| OPC UA | Modern PLCs and secure plant networks | Standard, encrypted machine-to-machine data exchange |
| MQTT | Lightweight, high-frequency or remote data | Publish/subscribe messaging through a broker to ThingWorx |
| REST / ERP APIs | SAP, MES and enterprise systems | Two-way integration of orders, assets and maintenance data |

FAQs
ThingWorx IIoT is the use of PTC ThingWorx to connect industrial machines and sensors, collect their data in real time and turn it into dashboards, alerts and analytics.
ThingWorx usually connects to PLCs through Kepware (KEPServerEX), OPC UA or MQTT. These gateways read machine tags and send them to ThingWorx as live properties.
Yes. Legacy controllers can be connected through Kepware drivers, protocol converters or edge gateways, so older equipment can be monitored alongside new machines.
Predictive maintenance uses live and historical machine data in ThingWorx to spot trends and deviations, so maintenance teams act before a failure causes downtime.
Yes. ThingWorx dashboards can track electricity, gas, steam, water and solar KPIs, compare them to targets and add environmental context such as temperature and humidity.
It depends on the number of machines and protocols. PSPTechHub typically starts with one pilot line, then scales the proven architecture to more lines and plants.
Yes. PSPTechHub provides ThingWorx AMS support, enhancements, and platform upgrades and migrations after go-live.
