    PLC data collection

    Connect PLC events to SQL Server, and know whether they worked.

    Saving production data is only part of the job. The control system also needs a reliable answer when the database is slow, unavailable or rejects a request.

    What the integration needs to handle

    A dependable PLC-to-database interface has to do more than read a tag and insert a row.

    Structured inputs

    Collect the values that belong to a transaction, including the product ID, operation, measurements and result. Keep mappings understandable as projects change.

    Explicit completion

    Return outputs and status to the PLC after the configured operation runs. The machine sequence should respond to the result, not assume a trigger means the transaction succeeded.

    Useful diagnostics

    Inspect collection, database work and PLC write-back separately. That distinction matters when production is waiting for an acknowledgement.

    A straightforward evaluation

    1. Choose one eventPick a representative controller, payload and SQL operation.
    2. Define the handshakeAgree on completion codes, timeouts, retries and duplicate protection.
    3. Test failuresDisconnect the database, interrupt write-back and verify what the PLC does next.

    Where Event Engine® fits

    Event Engine® can connect to supported Rockwell and Siemens controllers, Modbus/TCP devices, and OPC UA servers. It supports SQL Server and Oracle database operations, with a Windows host running the service.

    For Rockwell Logix applications, supported L5X structure import can reduce repetitive mapping. Siemens S7 support in the documented release uses absolute addressing; symbolic or optimized addressing is not supported.

    Event Engine® provides the transaction mechanism and telemetry. Your stored procedures, PLC handshake, network and recovery logic still determine the application's final behavior.
