The Pro Series controllers are programmed using VPL, an IEC 61131-3 ST (structured text) compliant language. VPL is structured, easy to understand and the standard for PLC programming. In the integrated development environment you will find everything you need: A powerful editor with syntax support, online documentation and a code wizard. A full-featured simulator allows extensive debugging without hardware. The debugger supports both local debugging in the target hardware (via USB or RS-232) and worldwide remote debugging via the Communication Hub. An uploader for application programs and also firmware completes the package.
