Breaking through the architecture of HMI hardware and software, we freed HMI from its traditional combination with LCD panel and touch screen, and perfectly integrated HMI’s visual control into iPad with the powerful EasyBuilder project editor software. Not only do we inherit the advantage of traditional HMI and the motto of “Make Things Easy,” we also encourage infinite innovation in HMI technology and lead HMI into the cloud. FEATURE ● Multiple iPad Clients A cMT-SVR can be operated by three iPads simultaneously, and by Account Management in EasyBuilder, user accounts and access privileges can be managed properly. ● One iPad, Multiple cMT-SVRs An iPad can connect to operate up to 253 cMT-SVRs, and 3 of the connected cMT-SVRs can be set as hot projects for instant switch in operation. ● Break with Tradition Embrace the Trend Through the integration of iPad and EasyBuilder, cMT Viewer, requiring no additional learning, break the public image of traditional HMI operation. By multi-touch-gesture-enabled Trend Display, Data Display, etc., you can immediately experience fluid and vivid visualization as well as the most intuitive HMI operation.
