Siemens SIMATIC HMI Basic Panel Series Technical Notes

The Evolution of SIMATIC HMI Basic Panel Architecture

The SIMATIC HMI Basic Panel lineage traces to the early 2000s OP/TP series (OP7, OP17, TP170), which relied on MPI and PROFIBUS DP as primary fieldbus interfaces. These units used proprietary display controllers and were configured via WinCC flexible, a standalone engineering tool. With the introduction of TIA Portal V11 (circa 2012), Siemens unified HMI engineering under a single framework and launched the first-generation KTP Basic Panels (KTP400, KTP600, KTP1000), which introduced resistive touch combined with physical function keys — a design retained through current generations for gloved-hand operation compatibility.

The second-generation Basic Panels (post-2016, identified by the 6AV2123-x ordering prefix) introduced PROFINET as the standard interface, replacing MPI as the default protocol. Display resolution improved to WVGA (800×480) on the KTP700 and larger variants. The current 6AV2123-2GA03-0AX0 (KTP700 Basic, 7" WVGA, PROFINET) represents the mature, production-stable revision of this generation. Compatibility with WinCC Basic (bundled with TIA Portal) and support for up to 500 tags define the operational ceiling of this product class. Successor migration paths lead to the SIMATIC HMI Comfort Panel series (6AV2124-x) for applications requiring higher tag counts, scripting, or multi-touch capability.
