This is the object to form groups of parameters in a block. One advantage of forming groups of parameters
is the reduction of load for data transaction. The EXA has four View Objects for each Resource block,
Transducer block and AI1, AI2, AI3 function block, and each View Object has the parameters listed in Table
3.12 to 3.14.
