Rievtech HMI Panels | Software Rievtech Studio Rievtech Studio is used to create projects that can display information from a PLC, process status, or can be used to input data with virtual switches or keypads to make changes to a process. Each screen can be designed and built in minutes using ‘drag and drop’ graphical objects found in the application library. Built-in Serial and Networking Protocols, this will allow Rievtech HMI to locally or remotely communicate with Rievtech or other major brand PLC manufacturers. 19
