5.6.3 View Objects

View objects are used to group parameters.
This reduces the load of data transactions. Each
digitalYEWFLO supports four view objects for each
of the Resource block, Transducer block, three AI
blocks, two DI blocks, one IT block, one AR block,
and PID block (option /LC1). Each view object
contains a group of the parameters listed in Tables
5.11 to 5.17.
Table 5.10 Purpose of Each View Object
VIEW_1 Set of dynamic parameters required by operator for
plant operation. (PV, SV, OUT, Mode etc.)
VIEW_2 Set of static parameters which need to be shown to
plant operator at once. (Range etc.)
VIEW_3 Set of all the dynamic parameters.
VIEW_4 Set of static parameters for configuration or
maintenance.

5.6.4 Function Block Parameters
