ENSEL_MS: Enable selector multistate
Block ENSEL_MS (FB453) as a central block allows for selective interconnection of one of 25 multistate values (1 of 25) to a particular priority.
Functionality
To interconnect multiple multistate values to a particular priority, block ENSEL_MS routes one of the 25 multistate inputs [Val1..25] to output [Value].
The following conditions apply:
- A multistate signal is available at the corresponding value input (Off..Stage15).
- The corresponding value input [Val1..25] = Off..Stage15 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 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).
