Siemens SIMATIC Basic Panel and Samkoon HMI: technical alternative selection guide
Compare Siemens KTP Basic Panels with Samkoon EA/SK HMI candidates by display, communications, software, panel cut-out and project migration.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
Samkoon EA and SK panels can be evaluated for basic machine visualisation when display size and communication requirements can be reselected. The KTP project, TIA Portal objects and Siemens communications configuration do not transfer directly; the panel, PLC driver and acceptance tests require re-engineering.

ProControl products to evaluate first
The exact configuration is selected after engineering review.
EA-070B V4
Basic 7-inch HMI candidate; Ethernet requirement and exact port layout are checked from the model document.

SK-102CS
10.2-inch 1024×600 candidate with Ethernet and serial communications, assessed for the larger-screen class.

Similar requirement, different architecture
The table explains product architectures; it is not an exact order-code selection.
| Validation area | Siemens SIMATIC HMI Basic Panels 2nd Generation | Samkoon / ProControl candidate |
|---|---|---|
| Display family | The Basic Panels 2nd Generation family includes display classes such as KTP400, KTP700, KTP900 and KTP1200; resolution and suffix are read from the exact order code. | EA-043A V4 is in the 4.3-inch/480×272 class, EA-070B V4 in the 7-inch/800×480 class and SK-102CS in the 10.2-inch/1024×600 class; selection uses usable screen area rather than the legacy panel name. |
| PLC and network connection | Siemens Basic Panel variants may target PROFINET or PROFIBUS; the actual interface varies with the KTP order code. | On EA and SK candidates, serial ports, Ethernet and the supported PLC driver are selected per model; the Siemens protocol role is not assumed. |
| Engineering software | KTP screens are engineered with the WinCC/TIA Portal project structure, device profile and Siemens tag/alarm objects. | The Samkoon screen is rebuilt in SKTOOL; page objects, tag addresses, alarms, recipes and user permissions are defined again. |
| HMI function scope | Alarm, trend, recipe, user-management and archive limits depend on the selected KTP model and TIA version. | Matching function names are insufficient; the SKTOOL object, logging capacity, history behaviour and export method are verified in a prototype project. |
| Mechanical and environmental fit | KTP enclosure dimensions, cut-out, mounting depth, supply and front protection are defined in the exact model document. | The Samkoon candidate's cut-out, connector orientation, 12/24 VDC supply range, temperature and front IP rating are independently verified from drawings and the data sheet. |
| Migration and acceptance | The existing WinCC project is part of the machine together with PLC symbols, screen navigation and operator habits. | Automatic project conversion is not assumed; screens, PLC write permissions, alarm/recipe behaviour, restart behaviour and cycle time are approved by FAT. |
Suitable scenario
When is it worth evaluating?
- New or redesignable machines where retaining TIA Portal dependency is not mandatory
- Operator panels needing basic screens, alarms, recipes and standard PLC communications
- Cost-controlled projects where panel cut-out and PLC driver can be redesigned
Migration gate
Before making a decision
- Record the full KTP order code and its PROFINET/PROFIBUS role.
- Inventory all used screens, pop-ups, tags, alarms, recipes and user levels.
- Confirm resolution, panel cut-out, mounting depth and ports for the Samkoon model from its drawing.
- Test the PLC addressing driver, data types, byte order and communication-loss behaviour.
- Approve write permissions, alarm history, restart and operator scenarios in a loaded-machine FAT.
Frequently asked
Clear answers about alternatives and migration
Is this a drop-in replacement?
No. It is not a direct substitute until exact model, electrical, protocol-role, mechanical, software and certification checks pass.
What should I provide for selection?
The exact existing code, diagram or I/O list, PLC/network data, supply, environment and special functions in use.
Can the KTP project in TIA Portal be converted directly to SKTOOL?
No. The screen and tag inventory can be used as a source, but the interface, communications and functions are rebuilt and tested in SKTOOL.

This content compares manufacturer-published data under the same project requirement; it does not guarantee direct substitution or project compatibility. ProControl engineering must validate exact model, revision, protocol, electrical, safety and environmental conditions.
