Compact, widely applicable and cost-effective, the 7” HMI has always been one of the most popular products. That is why Weintek is introducing a new 7” HMI: the cMT3071. The new model aims to make the cMT series a realistic option for more and more of our customers building the smart factories of the future with the features cMT models offer. At first glance, the cMT3071 enjoys higher hardware specifications than its counterparts in the IE / iP / eMT series in every respect, promising better computing performance and an experience users have not had before. Fitted with a 1 GHz Cortex A9 dual-core processor, 4 GB Flash and 1 GB RAM, the cMT3071 runs more smoothly, allows a project with a richer set of features, and offers more storage space for saved data. What is more, the cMT3071 uses not only the same cut-out size as the 7“ iE / iP / eMT series, but also the same screen resolution, 800 x 480. Little or no change is needed to existing hardware and software, which saves labour and cost and makes moving to the cMT3071 the natural choice. The cMT3071 comes with the following innovative features developed by Weintek:
| The cMT architecture: multi-display and remote monitoring | Token Control as security management |
| Besides monitoring on the HMI screens, by running the cMT Viewer application on a Windows, iOS or Android device, operators can monitor and control several cMT HMIs wirelessly. | Token Control on key objects makes sure only one client can operate the device at a time. Potential conflicts that can arise when a device is monitored from several devices are avoided. |
| The IIoT answer | The HMI + CODESYS answer |
| Supports the standard IIoT protocols, MQTT and OPC UA, and connection to an SQL database. | CODESYS can optionally turn the HMI into a high-performance PLC compliant with IEC61131-3. Combining HMI + CODESYS with the “iR” range of I/O modules gives a next-generation answer with a more flexible architecture. |
