Parameter indexing
When certain parameters apply to more than one input or output, an index selector
parameter is used. The index selector parameter defines the measurement signal path for
each input or output of its applicable parameter.
The Level Selector is the most commonly used index selector parameter; it is required for
almost all inputs and outputs. In the illustration below, Level Selector (2.1.2.) (Page 162)
assigns the Point (Level 1, 2 or 3) to the succeeding options to be made, such as transducer
number [Transducer selector (2.1.4.) (Page 164)] and transducer type [Transducer (2.1.5.)
(Page 164)].
The block diagram below traces an example signal path where an input is scaled and
converted into an output, using various index selector parameters [Transducer Selector
(2.1.4.) (Page 164), Level Selector (2.1.2.) (Page 162), mA Output Selector (2.5.1.)
(Page 180), and Relay Selector (2.8.1.1.) (Page 193)]
