FAQ
Frequently Asked Questions
Answers to common questions about protocol support, edition differences, licensing, and industrial deployment scenarios.
Which industrial protocols does MThings support?
MThings supports MODBUS ASCII, RTU, TCP, and TCP/UDP passthrough, as well as Siemens S7 and DL/T 645-2007, for integrating PLCs, meters, inverters, and similar devices.
What is the difference between the personal and commercial editions?
The personal edition is free for individual debugging, simulation, testing, and learning. The commercial edition is licensed for enterprise deployment and adds SCADA monitoring, historical data, industrial alarms, data gateway, and related commercial-use capabilities.
Which industrial devices and deployment scenarios is it suitable for?
MThings can be used with PLCs, meters, inverters, touchscreens, IPCs, and other industrial control devices, and is suitable for multi-protocol monitoring, on-site debugging, and data gateway projects.
When is a commercial license required?
A commercial license is required when MThings is used for enterprise operations, commercial projects, system integration or customer delivery, paid services, or production and monitoring systems that run continuously.
Do I need a paid license for personal office work and debugging?
No. Personal, non-commercial office work, device debugging, simulation, testing, and learning are free. A commercial license is required if the work supports an enterprise project, customer delivery, or business operations.
Is the commercial license a one-time purchase or a subscription?
The commercial license is a one-time purchase rather than a monthly or annual subscription. Once authorized, the corresponding software version can be used permanently.
Is the license tied to a computer, and can it be transferred when replacing the computer?
The commercial license is associated with the authorized computer. For a normal computer replacement, contact technical support with the original license and new-device information to request a license transfer. Transfer eligibility is subject to the current licensing policy.
Can MThings run offline?
Yes. After installation and authorization, core functions such as device communication, monitoring, and data acquisition do not require a continuous internet connection. Internet access may still be needed for downloads, updates, and online support.
Which Siemens S7 PLCs and connection methods are supported?
MThings supports Ethernet communication with commonly used Siemens S7-200, S7-200 SMART, S7-300, S7-400, S7-1200, and S7-1500 PLCs. Compatibility can vary with the CPU, firmware, and network configuration, so verification with the actual device is recommended before deployment.
