The operator panel HT300 with touch screen is a smart and simple way how to operate the free-programmable process stations using SoftPLC or Domat runtime. Its LCD display shows a tree menu structure, created for the PLC LCD displays, in the Domat Menu Reader application, or displays simple plant graphics with active objects in panels, which are engineered as web pages for the PLC web servers. The application engineers do not need to install and work with new programs, a single HMI project suits both local operation over a PLC display and remote operation over the HT300 terminal.
