Weintek cMT X and Samkoon SK: a selection guide separating HMI and IIoT requirements
Compare Weintek cMT X with Samkoon SK HMI candidates by display, network separation, OPC UA/MQTT, remote clients and project migration.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
Samkoon SK can be evaluated for machine-level local visualisation and standard PLC communications. If the cMT X project uses OPC UA, MQTT, dual networks, cMT Viewer or data integration, matching the screen size is insufficient; every function must be proven on the exact Samkoon model and software.

Similar requirement, different architecture
The table explains product architectures; it is not an exact order-code selection.
| Validation area | Weintek cMT X Standard | Samkoon / ProControl candidate |
|---|---|---|
| Display and processing class | The cMT X Standard family uses different display sizes and multicore platforms for advanced visualisation/connectivity tasks; exact hardware depends on the model. | SK-070MS V3, SK-102CS and SK-156QS-G are local-HMI candidates across the 7–15.6-inch range; processor, memory and resolution are verified from the exact model page. |
| Network separation and ports | cMT X models vary across single/dual Ethernet, serial, CAN, USB and SD options; dual networks can separate machine and upper-level networks. | Ethernet and serial ports on Samkoon candidates are taken from the exact model. A single-Ethernet panel is not automatically a candidate where two physical networks must be separated. |
| OPC UA, MQTT and data layer | Weintek positions the cMT X family with OPC UA, MQTT and data-integration functions; support and licensing depend on the exact model/software. | These protocols are credited to Samkoon only after verification in the model document, SKTOOL version and a working PoC. A separate edge-gateway architecture is designed if required. |
| Remote client and maintenance | cMT Viewer, VNC and remote-maintenance capabilities are assessed with the selected cMT model's firmware and security settings. | The same experience is not assumed for Samkoon; remote-access method, user authentication, encryption, session logging and network boundary are tested separately. |
| Project environment | cMT X screens are developed with EasyBuilder Pro objects, drivers, macros and data models. | The SKTOOL project is built from scratch; addressing, scripts, alarms, recipes and logging behaviour are not assumed to transfer one-to-one. |
| Cybersecurity and acceptance | cMT X network services fall within a security scope covering users, certificates, ports and firmware policies. | In the new architecture, unused services are disabled; VLAN/firewall, user roles, backup, connection loss and data integrity enter acceptance testing. |
Suitable scenario
When is it worth evaluating?
- Machines whose core need is a local operator screen and standard PLC connection
- Redesigns where IIoT functions can move to a separate edge gateway
- OEM projects where network, security and remote-access architecture can be revalidated from the ground up
Migration gate
Before making a decision
- Identify the exact cMT model, Ethernet-port count and used serial/CAN/USB/SD interfaces.
- Document OPC UA, MQTT, SQL, cMT Viewer, VNC and remote-maintenance use separately.
- Confirm required protocols and services on the exact Samkoon model in official documentation and a working PoC.
- Redesign EasyBuilder Pro macros, addressing, alarms, recipes and data logging.
- Complete cybersecurity, network-loss, time-synchronisation, data-loss and restore tests.
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.
Does a Samkoon SK panel automatically cover the OPC UA and MQTT duties of cMT X?
No. These functions are not treated as covered unless officially documented and proven by a PoC on the exact model and software; a separate gateway is used when necessary.

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.
