Siemens 6AV6648-1AC22-0AX0 KTP1000 Basic PN Upgrade Solution

Product Overview

Siemens 6AV6648-1AC22-0AX0 KTP1000 Basic PN: Seamless Upgrade & Replacement Solution

The Siemens 6AV6648-1AC22-0AX0 — commercially designated as the KTP1000 Basic PN — is a 10-inch widescreen key-and-touch HMI panel from the SIMATIC HMI Basic Panel 2nd Generation family. As legacy SIMATIC HMI systems age out of Siemens’ active support lifecycle, many industrial facilities operating older OP/TP/MP series panels or first-generation Basic Panels are now planning structured migrations to maintain uptime, comply with cybersecurity requirements, and leverage modern PROFINET-based control architectures. This product page is designed to support engineers and procurement teams executing exactly that transition — providing full compatibility context, upgrade guidance, and sourcing assurance for the 6AV6648-1AC22-0AX0.

Seamless Upgrade Solutions

A successful migration to the 6AV6648-1AC22-0AX0 rarely involves the HMI panel alone. In most retrofit projects, the panel replacement is part of a broader control system modernization that touches multiple layers of the automation architecture.

On the controller side, facilities migrating from S7-300 or S7-400 platforms typically pair this HMI upgrade with a transition to a SIMATIC S7-1500 CPU — such as the CPU 1515-2 PN — or a compact S7-1200 CPU 1214C DC/DC/DC for smaller machine cells. The KTP1000 Basic PN communicates natively with both via PROFINET, eliminating the need for protocol converters or additional communication modules that older MPI/PROFIBUS-based HMIs required.

For distributed I/O architectures, the panel integrates cleanly into systems using SIMATIC ET 200SP or ET 200MP remote I/O stations. If your existing cabinet uses a SM 321 / SM 322 digital I/O module on an S7-300 rack, the migration path typically involves remapping those signals to ET 200SP BaseUnits with appropriate I/O modules, all managed through TIA Portal — the same engineering environment used to configure the KTP1000 Basic PN.

Power distribution within the control cabinet should also be reviewed. The SITOP PSU100S 24V/10A power supply module is a common companion in modernized cabinets, providing stable 24 V DC to both the HMI panel and the controller rack. Its slim DIN-rail form factor makes it well-suited for space-constrained enclosures where the KTP1000 Basic PN is being retrofitted alongside a new CPU.

Communication infrastructure upgrades often accompany HMI replacements. If the legacy system used a CP 343-1 Ethernet module for S7-300 PROFINET connectivity, that module becomes redundant once the new CPU provides integrated PROFINET ports. Similarly, if the plant network requires managed switching, a SCALANCE X208 industrial Ethernet switch can be added to the cabinet to support the panel’s integrated two-port PROFINET switch and maintain network segmentation.

For projects where the existing HMI project was developed in WinCC flexible, Siemens provides a migration wizard within TIA Portal to convert legacy screens to the Basic Panel format. However, engineers should note that certain advanced scripting or VB script functions from WinCC flexible are not directly portable — a partial screen rebuild is often required. During this phase, having a PC Adapter USB A2 or SIMATIC NET CP 5711 programming cable on hand ensures uninterrupted communication between the engineering station and any remaining S7-300 PLCs still online during the transition period.

Finally, for facilities that operate SINAMICS G120 or MICROMASTER 440 variable frequency drives connected to the legacy HMI via fieldbus, the migration to PROFINET-based communication with the KTP1000 Basic PN may require a PROFINET interface module (CBE20) for the G120 drive or a protocol gateway for older MM440 units. Addressing drive communication compatibility early in the project plan prevents commissioning delays and ensures the new HMI can display drive status, fault codes, and speed references as expected.

Retrofit Guidance FAQ

Q: Can the 6AV6648-1AC22-0AX0 replace my existing KTP1000 Basic PN Gen 1 without a panel cutout modification?
A: In most cases, yes. The 2nd Generation KTP1000 Basic PN shares the same 260 × 200 mm panel cutout as its predecessor. Verify the exact cutout dimensions of your existing installation before ordering.

Q: Is the existing WinCC flexible project compatible with TIA Portal for this panel?
A: TIA Portal includes a migration tool for WinCC flexible projects. Basic screen objects, tags, and alarms migrate well; advanced VB scripts and certain dynamic dialogs may require manual rework. Budget 1–3 engineering days for a typical 50-screen project.

Q: What PROFINET configuration is required?
A: The panel must be assigned a unique PROFINET device name and IP address within TIA Portal’s hardware configuration. It connects directly to the CPU’s PROFINET interface or to a managed switch on the same subnet. No additional communication modules are required.

Q: Can this panel communicate with an S7-300 PLC?
A: Yes, provided the S7-300 CPU has an integrated PROFINET port (e.g., CPU 315-2 PN/DP) or a CP 343-1 Advanced communication module. MPI/PROFIBUS-only CPUs are not directly supported.

Q: What are the physical installation requirements?
A: Panel cutout: 260 × 200 mm. Mounting depth behind panel: approximately 45 mm. Power: 24 V DC ±20%, 4.5 W. Ambient temperature: 0–50 °C (operating). IP65 front protection when properly sealed with the supplied gasket.

Q: How do I handle the transition period when both old and new systems are running simultaneously?
A: Plan a parallel-run window of 24–72 hours where the new HMI is configured and tested offline before cutover. Use the existing panel for live production monitoring while the new unit is commissioned on a test bench or staging rack.

Warranty Assurance
