FAQs

Q1: What are the standard HMI sizes available in your product line?

A: Our Standard HMI sizes include 3.5, 4.3, 5, 7, 10.2, and 15.6 inches.

Q2: What is the verified hardware environmental protection rating of the front bezel?

A: All standard models feature a certified IP65 front panel protection rating.

Q3: Does the SK Series HMI support IoT remote monitoring?

A: Yes. Plug-and-play IoT expansion module (Wi-Fi/4G) supports VNC remote monitoring, Display Control Cloud 3.0, and remote PLC program transparent transmission.

Q4: Does the HMI support communication with other brands of PLC?

A: Yes, supports over 300 PLC protocols, compatible with mainstream brands such as Siemens, Mitsubishi, and Omron.

Q5: Does the HMI support multi-language and recipe functions?

A: Supports 50 languages, multi-group recipes, multi-window display, data alarms, and C-language macros.

Q1: Does the SKTOOL software support my local language for project development?

A: Yes. While the system interface natively supports 4 languages (English, Russian, Turkish, and Chinese), the underlying programming environment utilizes a broad Unicode configuration that completely supports most global languages for all project texts and runtime labels.

Q2: Is there a licensing fee or subscription required for the SKTOOL configuration software?

A: No. SKTOOL is completely free and full-featured from day one. There are no annual subscriptions, activation fees, or hidden paywalls for advanced communication drivers.

Q3: Can I run SKTOOL on a Linux or macOS development environment?

A: No. SKTOOL is natively compiled for the Windows operating system architecture. 

Q4: Does the software support runtime multi-language switching?

A: Yes. You can configure the interface to switch between up to 4 pre-loaded system languages instantly at runtime via field-button triggers or PLC register variables.

Q5: How do I update the HMI communication protocols to the latest PLC drivers?

A: New protocol drivers are packaged directly into our periodic SKTOOL software updates. Simply download and install the latest software version to refresh your local driver library.

Q1: Is there a Minimum Order Quantity (MOQ) restriction for standard hardware units?

A: For standard hardware configurations, there is zero MOQ restriction. Samples can be ordered starting from a single unit to facilitate rapid field evaluation.

Q2: How do you protect local distributors from direct market undercut from third parties?

A: We operate on a transparent regional distribution hierarchy. Certified territorial channel partners receive distinct price structures, protected leads, and direct project registration tracking to secure local project margins.

Q3: Can we request custom brand labeling (OEM white-labeling) on the hardware bezel?

A: Yes. We offer customized front-bezel overlay printing and custom boot-logo flash options for qualified high-volume OEMs and regional distribution partners subject to annual volume agreements.

Q4: What is the standard manufacturing and shipping lead time for volume procurement?

A: Standard configurations are maintained in stock for immediate dispatch. Bulk volume batches up to 500 units are typically manufactured, quality-certified, and ready for global freight within 10 to 15 business days.

Q1: What is the standard factory warranty period provided?

A: All standard units come with a 18-month factory warranty covering component material integrity and manufacturing defects, calculated from the original date of shipping dispatch.

Q2: What is the standard protocol if a hardware unit suffers a field component failure?

A: Contact your regional distributor or file an online ticket. If verified as a warranty defect, we provide rapid-exchange component modules or factory repair alignment according to our standard service level agreements.

Q3: How can I troubleshoot a persistent “Communication Timeout” error on the display?

A: Verify physical cable pinouts against the SKTOOL manual, confirm that the communication station IDs match the master PLC registers, and check for appropriate terminating resistors on long RS-485 runs.

Q4: Do you offer free hardware repair parts to authorized distributor repair depots?

A: Yes. Contracted regional distributors receive allocated service part kits (including replacement touch overlays, power boards, and LCD modules) alongside advanced technical diagnostic training.

Q5: Is technical support available for setting up third-party Modbus RTU/TCP bridging?

A: Yes. We provide step-by-step documentation, wiring diagrams, and pre-configured SKTOOL template files for standard Modbus configurations to minimize your integration development time.
