Structure Data Type Definitions - OpPrty
Structure data types serve as the major input and output data carriers between different function blocks, configuration, and parameterization data.
The following section lists the names of structures (data types) that are used in this function block, followed by a table that describes the elements of structure.
NOTE: For the structure data types that are used from this function block and others, refer to the Common Structure Data Type Definitions chapter.
The stUsrTbl structure data type contains the user-defined priority table. It allows you to assign a priority value to each of the 8 pumps or VSDs:
|
