New Product Announcement – cMT3071 – 7″ HMI

Product Introduction and Features

Being compact and cost-effective, Weintek 7” HMI have always been a popular product. With that in mind, Weintek have introduced a new 7” HMI: cMT3071. The new model aims to make cMT Series models a more accessible option allowing more of our customers to build their smart factories using cMT’s rich, powerful features.

The cMT3071 boasts higher hardware spec than its iE/iP/eMT Series counterparts in every aspect, with better computational performance it delivers a richer user experience. Equipped with a dual-core Cortex A9 1GHz CPU, 4GB Flash and 1GB RAM, the cMT3071 runs more smoothly, allows projects with richer sets of features, and provides more storage for historical data. Furthermore, cMT3071 is a great choice for cMT series adoption as it uses not only the same cutout dimension as 7″ iE/iP/eMT series, but also the same screen resolution at 800 x 480 so it requires little or no modification to existing hardware and software, saving both development time and cost ensuring seamless migration to cMT3071.

cMT3071 supports all of the following innovative features developed by Weintek:

cMT Architecture: Multi-display & Remote Monitoring Control Token as Security Management
Apart from monitoring on HMI screens, by running cMT Viewer App on a Windows, iOS, or Android device, the operators are able to wirelessly monitor and control multiple cMT HMIs. Control Token set for key objects can ensure that only one client may operate the device at a time Potential conflicts which may arise when the device is monitored by multiple devices are avoided.
IIoT Solution HMI + CODESYS Solution
Supports the de-facto IIoT protocols standard: MQTT and OPC UA, and Sync Data to MySQL or MS SQL database. Optional CODESYS can turn HMI into a high-performance IEC61131-3 compliant PLC. Combining HMI+CODESYS with I/O modules delivers a new generation solution that achieves a more flexible architecture. (requires CODESYS Licence Card)
