There are many control companies, each with their own control language. I know six different control languages myself (Carrier CCN, Honeywell Excel, Andover, Siemens-L&G PPCL, Circon & AVG/EZAutomation Ladder Logic).
They all will perform the same sequence of operation if written correctly. If your question is how to interpret a language, please post an example and we will explain what the driven process is and how they are accomplishing that sequence. If you need direction in how to write a control sequence, then be specific in what your process is and the desired result.
