How It Works

Three simple steps technicians follow to securely access and operate through RoltekConnect Cloud.

  1. 1

    Connect

    Technician authenticates to RoltekConnect Cloud and requests access to a site.

  2. 2

    Authorize

    Admin approves access; just-in-time policies open the path to the target PLC/HMI.

  3. 3

    Operate

    Technician uses their native tooling (TIA Portal, Studio 5000, GX Works, etc.) over the encrypted session.

Compatibility

Works across leading PLC vendors, engineering tools, and industrial interfaces.
