UNITY PRODesign and develop applications for Modicon M340, Premium and Quantum PLC platforms using Unity Pro control software. Unity Pro is designed to enable users to develop functions using symbolic descriptions of data and an embedded library of derived function blocks (DFBs). This includes utilizing any of the five IEC-standard languages to customize your program. Online syntax verification in the textual and graphical language editors and the integrated PLC emulator debugging tool help to minimize programming errors. Functional views give direct access to the control management of the process.
