Functional test station for any product

When it makes sense

No standard station fits the product

Some products need a test that no supplier's standard machine covers. A general station makes sense when:

The product has no standard test line or off-the-shelf tester.
Every part needs a pass or fail check tied to its serial number.
Several bought instruments must run in one sequence and hand results to the PLC.

Hardware

What a functional station includes

The station drives whatever instruments the product needs and reads the part code through an OpenEOL code reader driver. It hands the pass or fail result and the record to the PLC and the MES.

Software

The open-source software behind it

Your plantReceives the results

MES and quality databaseResults over OPC UA, MQTT or SQL

OpenEOLRuns the station

Task engine Open sourceRuns the sequence in series, parallel or state machine mode

Operator GUI Open sourceRole-based screens for the operator, in several languages

Reports and database Open sourceOne record for each serial number

AnalysisJudges the result

Pass or fail logicLimits and screening written for the product

Order tracking and SPCEnvelope checks, band limits and SPC statistics, written per project

DriversTalk to the hardware

OpenEOL IO drivers Open sourceModbus, Siemens S7, Beckhoff ADS, OPC UA, MQTT, NI DAQmx or Dewesoft, chosen per instrument

Code reader drivers Open sourceBarcode and Data Matrix readers, among other OpenEOL drivers

Database driver Open sourceSQLAlchemy, for one record per serial number

The parts marked open source are code your team can read and change. Domain analysis, such as pass or fail limits and SPC checks, is written for each product.
