Trend Object

Trend Object
You can set the parameter so that the function block automatically transmits Trend.
FVP110 has seven non-factory set Trend objects, five for analog data, and two for
discrete data. A single Trend object specifies the trend of one parameter.
Each Trend object has the parameters listed in Table 16. The first four are settable.

View Object

This is the object to form groups of parameters in a block. One of advantages brought
by forming groups of parameters is the reduction of load for data transaction. FVP110
has 12 View objects for Transducer block and four View objects for each Resource, AO
and DI1 and DI2 function block, and each View object has the parameters listed in
Table 17 to Table 22.
