Quick verdict
If you are choosing between a PC-style HMI and a Siemens-native touch panel, the Parker IXA-000-3N3-53 IX InteractX PowerStation Industrial PC HMI and the 6AV2123-2GB03-0AX0 Siemens SIMATIC HMI KTP700 Touch Screen take two different paths. The Parker is the industrial PC unit, while the Siemens panel is the direct companion for a SIMATIC environment. At $200.00 versus $614.00, the price direction is clear, but the right pick depends on how much flexibility you need in screen design and which PLC platform you are working with.

Where the Parker wins
The Parker IX InteractX PowerStation is the more suitable choice if you want an HMI that acts like a PC. The InteractX development environment is built around visual design, with styles and templates that make it easy to keep screens consistent, plus a toolbin for saving and reusing custom tools or entire screens. It supports Ethernet, USB, and VGA connections, and its feature set includes bar graph display, data entry, real-time graphs, and programmability. That combination is useful if your operators need data-rich views and you plan to do your own screen development.
Where the Siemens wins
The Siemens SIMATIC KTP700 Touch Screen is the more direct fit in an automation environment built around the S7/300 controller platform. It is a SIMATIC HMI panel, so it belongs in the same product family as the controllers it is meant to work with. The panel supports AC current and lists SSD as a supported drive type, and it comes with firmware revision V02 20. If you want a dedicated touch screen rather than a general-purpose industrial PC, this is the cleaner integration path.
A closer look at each HMI
Parker IXA-000-3N3-53 IX InteractX PowerStation
The Parker IXA-000-3N3-53 IX InteractX PowerStation gives you a Windows HMI you can program without special IT skills, thanks to InteractX's styles and templates. That is the main reason to choose it for a custom screen build. Its Ethernet, USB, and VGA connections are useful for older and newer control equipment, and the real-time graph support helps operators see live trends. The trade-off is that this is a used unit, and the SSD cover is missing one screw. If a pre-owned industrial PC HMI with a flexible development environment fits your project, this is a practical starting point.
Siemens SIMATIC HMI KTP700 Touch Screen
The 6AV2123-2GB03-0AX0 Siemens SIMATIC HMI KTP700 Touch Screen is the one to pick when you want a panel that matches the S7/300 platform. The panel supports AC current and solid-state drives, and the firmware revision is V02 20. For a Siemens-centric control cabinet, that kind of compatibility removes a lot of integration guesswork. The limitation is that it is a touch screen rather than an industrial PC, so if your application depends on building custom Windows screens outside the Siemens environment, the Parker unit has more flexibility. For a straightforward SIMATIC installation, the KTP700 is the more direct choice.
Final choice by use case
For a flexible, data-rich HMI with screen design options, choose the Parker IX InteractX PowerStation. For a Siemens-centric environment where a dedicated SIMATIC touch panel is the cleaner fit, choose the Siemens SIMATIC HMI KTP700. If you need to build and customize screens and want broad design flexibility, the Parker is the one; if you want a panel that matches a Siemens system, the KTP700 is the intended match.
