DENC Digital Encoder Function Block
Description
The DENC label stands for Digital Encoder.
This block is part of the
Auxiliary category.
Function
This block’s main function is to totalize the number of ON states from up to 16 digital signals. The block
digitally encodes up to 16 digital inputs to a single floating point output value.
Forcing of the output is not permitted.
Inputs
Sixteen digital inputs: Example: ON causes the input to be included in the total output. Unconnected pins
default to OFF.
IN 1 = Digital Input 1 IN 9 = Digital Input 9
IN 2 = Digital Input 2 IN 10 = Digital Input 10
IN 3 = Digital Input 3 IN 11 = Digital Input 11
IN 4 = Digital Input 4 IN 12 = Digital Input 12
IN 5 = Digital Input 5 IN 13 = Digital Input 13
IN 6 = Digital Input 6 IN 14 = Digital Input 14
IN 7 = Digital Input 7 IN 15 = Digital Input 15
IN 8 = Digital Input 8 IN 16 = Digital Input 16
