ENSEL_R: Enable selector real

Block ENSEL_R (FB458) as a central block allows for selective interconnection of one of 25 real values (1 of 25) to a particular priority.

Functionality

To interconnect multiple real values to a particular priority, block ENSEL_R routes one of the 25 real inputs [Val1..25] to output [Value].

The following conditions apply:

• A real signal is available at the corresponding value input.
• The corresponding value input [Val1..25] = "Value" is enabled by the corresponding enabling pin [En1..25] = 1 (Yes).
• There is no higher-value input [Val1..25] at output [Value].
• If multiple value inputs [Val1..25] are enabled [En1..25], the pin with the highest priority (lowest number) is switched to output [Value].
• Output [InNr] contains an integer number according to the number of the input [Val] routed to output [Value].
• If all enable pins [En1..25] = 0 (No), output [Value] is set to the default value [DefVal].
• If the output [Value] represents a valid value, output [Enable] = 1 (Yes).
