Usage Scenario

Production Line Andon and Status Notification

Create Andon lamp, central panel and production event records by reading machine status contacts.

Make status data visible

Appropriate machine contacts such as running, waiting and fault can be read on the digital inputs. While NetRelay triggers the local Andon lamp, it can relay the same event to the central software via MQTT or HTTP.

Data quality

Contact meanings must be verified with the machine manufacturer, and filtering must be applied for short pulses. NetRelay should be used as an auxiliary state collection layer without interfering with the machine's safety PLC.
