Modbus TCP / RTU
Read device registers, discrete values and status data from common PLCs and instruments
Industrial observability
Connect production equipment, control systems and edge collectors through industrial protocols including Modbus, OPC UA and MQTT. Bring equipment metrics and exception events into one observability platform.
Read-only collection leaves field control logic unchanged while supporting production safety and data visibility.

Read device registers, discrete values and status data from common PLCs and instruments
Use subscriptions or compatible polling while retaining device data quality status
Support encrypted transport and message delivery quality levels for JSON and text data
Organize signals by device and production line, retaining collection timestamps and business tags
01 / PROTOCOLS
Collect equipment status, metrics and exception events near the source without changing existing control systems, then send them to Guance for querying, analysis and alerting.
Connect control cabinets, PLCs, instruments and production equipment using existing protocols and network conditions. View operational signals across devices and production lines in one platform.
The solution collects equipment status and production data without sending control commands to PLCs or control systems.

02 / DATA FLOW
Keep recording and forwarding device data through network fluctuations, device differences and traffic peaks. See where data comes from and its current status.
PLCs, instruments, control cabinets and production equipment
Handle industrial protocols, data preparation and offline buffering
Aggregate field data and forward it reliably to Guance
View equipment status, exception events, trends and alerts
The edge collector prepares, compresses and temporarily stores data, then resumes transfer when connectivity returns. Data types are isolated so that an individual device failure does not block the entire collection path.
03 / VALIDATION
Sustained load testing evaluates processing capacity, resource use and data integrity when many devices report data at the same time.
Data points processed per second
Above the 20,000 points/s test targetSeconds of continuous operation

Both zero during the testThese results come from a simulated MQTT load test of sustained high-throughput collection. Actual project results depend on device count, protocol configuration, network conditions and deployment specifications. Validate the solution in the customer environment before production rollout.
04 / SCOPE
The solution focuses on read-only industrial data collection, reliable forwarding and unified analysis. It does not replace field control systems or write to devices.
Collect data through Modbus TCP/RTU, OPC UA and MQTT, and analyze it in Guance.
No device control, parameter delivery, register writes or control-loop write-back.
Complete integration and acceptance testing against actual device models, certificate policies, network conditions and operating systems.
GUANCE INDUSTRIAL OBSERVABILITY
Connect data from field devices and control systems in Guance to help production, equipment and operations teams detect anomalies and investigate problems.
