HMI & Operator Interface
Two new graphic HMIs
Maple Systems has just added two new Touchscreen Graphic HMIs to its family of OIT products. The new HMI5043T is a compact 10.9-cm 16:9 widescreen model, and the HMI5104TH is a larger 26.4-cm high-resolution unit. Both units have an Ethernet port and VNC server that enables the user to remotely monitor and control the HMI, and thus PLCs and controllers, from any location via desktop computer, laptop, cell phone or any other smart device that has Internet connectivity. The 16:9 widescreen high-resolution display of the 10.9-cm model offers 30 percent more viewing area than a standard screen of similar size, the company says. The 10.9-cm unit has a high-brightness, high-contrast, backlit TFT display, and 480 by 272 pixel screen resolution. The larger unit has a 600 by 800 pixel screen. Both units have a 32-bit RISC processor, 128 MB of Flash storage and 64 MB of data memory. Connectivity of these units includes USB, Serial and Ethernet ports. Each unit contains an analog touchscreen with infinite touch-response points. Other features include online/offline simulation, alarm and recipe management, data logging and sampling, true-type fonts and multiple languages with international characters. These Maple HMIs are able to communicate with multiple controllers using different PLC protocols – allowing for easy integration to augment an existing system.
