direct result of the number of Select lines. The formula is
as follows:
# of Selection outputs = 2n (where n is the number of
Select inputs)
The maximum number of Select lines is eight.
Once you have determined how many select lines you
want, the assignments to these
Selector.Select lines must then be made in the
Assignments view.
For example, if the user enters 2 for the number of Selector
Input Destinations, we would have 4 Selection lines
(Selector.Selection0 through Selector.Selection3). The
Selector.Selection number that activates is determined by
the status of the Selector.Select lines when the
Selector.SelectorInitiate bit is activated. Each select line
has a specific binary value.
The binary value is determined as follows:
Sn x 2n where Sn = Status of Selector.Select line n
Sn = 0 if Selector.Select line n is inactive, and
Sn = 1 if Selector.Select line n is active
The sum of all the binary values determines which
Selector.Selection line will be active.
The following examples demonstrate how to determine
which Selector.Selection will activate based on the
Selector.Select lines.
Example 1:
If Selector.Select2 is active, Selector.Select1 is inactive,
and Selector.Select0 is active, then the total binary value is
as follows:
S2 = 1, S1 = 0, and S0 = 1. Therefore,
Total Binary Value = (1 x 22) + (0 x 21) + (1 x 20)
Total Binary Value = 4 + 0 + 1
Total Binary Value = 5
Therefore, when Selector.SelectorInitiate activates,
Selector.Selection5 will activate.
Example 2:
If Selector.Select2 is inactive, Selector.Select1 is active,
and Selector.Select0 is active, then the total binary value
would be as follows:
S2 = 0, S1 = 1, and S0 = 1. Therefore,
Total Binary Value = (0 x 22) + (1 x 21) + (1 x 20)
Total Binary Value = 0 + 2 + 1
Total Binary Value = 3
Therefore, when Selector.SelectorInitiate activates,
Selector.Selection3 will activate.
The Selector.Select lines can change without any action
until the Selector.SelectorInitiate destination is activated.
Selector.Selection sources can be tied to any destination in
the Assignments view. Figure 92 shows the four Selection
lines being assigned to Index 0 through Index 3 Initiates,
and the two Select lines being assigned to digital inputs. By
doing this, we could initiate up to four indexes with only two
Select lines and a Selector Initiate. This helps to minimize
the number of inputs required to initiate a large number of
indexes or programs.
