Programming DPIs



All PD 600 series DPIs are, like other PROCES-DATA Controllers, programmed in Process-Pascal, which is a high level programming language based on Standard Pascal.

The tools used to develop, compile, download and debug Process-Pascal programs are part of the VIGO Fieldbus Management System.



Process-Pascal programs are compiled using a cross-compiler running on a PC under different Windows environments. The compiler generates code, P-code, which is stored in the DPI in FLASH memory. The operating system in the DPI interprets the P-codes and executes a piece of machine code for each one.



The Process-Pascal program suite provides a debugger, which is a very powerful tool that significantly speeds up the entire process of an application development.
