The EPC1502 includes a preinstalled InfluxDB database. Use Edge Cockpit to open database administration, then establish the PLCnext-to-Node-RED-to-InfluxDB data path before building dashboards or alerts.

Open InfluxDB from Edge Cockpit

Connect to the EPC1502 and open Edge Cockpit at the default address 192.168.2.10/cockpit. Select the Database Administration tile to access the installed database. If the device address has been changed, use its configured address instead of the default.

Configure the Data Path

The documented data path moves PLCnext data through Node-RED and into InfluxDB. The available evidence does not identify PLC variables, Node-RED node settings, database names, buckets, credentials, or sampling intervals; obtain those project-specific values before configuring the flow.

  1. Identify the PLCnext data that must be recorded.
  2. Import the Node-RED flow supplied with the EPC first-project documentation.
  3. Configure the flow with the project-specific PLCnext and InfluxDB connection details.
  4. Run the flow and confirm that records appear in InfluxDB.

Visualize and Monitor Stored Data

After confirming data ingestion, locate the imported data in InfluxDB and create a dashboard from it. Alert management is also available, but define alert conditions only after verifying that the selected measurement and field update correctly.

Verification Checklist

Stage Verification
Edge Cockpit The Database Administration tile opens the database interface.
Node-RED The imported flow runs without a reported connection or write failure.
InfluxDB The intended PLCnext data appears and continues updating.
Dashboard The visualization displays the stored field over the selected time range.
Alert The configured condition evaluates against the intended measurement and field.

FAQ

Is InfluxDB preinstalled on the EPC1502?

Yes. The evidence states that the database comes preinstalled and is accessible through the Edge Cockpit Database Administration tile.

How do I open InfluxDB on an EPC1502?

Open 192.168.2.10/cockpit when the EPC1502 uses its default address, then select Database Administration. Use the device's configured address if the default has been changed.

How does PLCnext data reach InfluxDB on the EPC1502?

The documented path sends PLCnext data through Node-RED to InfluxDB. Import the supplied first-project Node-RED flow, enter the project-specific connection details, and verify that records update in InfluxDB before creating dashboards or alerts.
