Calculation
•
The output is calculated as input * Offset.
•
If the output result is greater than the data type concerned:
the maximum for the data type is applied to the output.
•
If the output result is less than the data type concerned:
the minimum for the data type is applied to the output.
The N-CONV element can be used to divide a 2-byte unsigned value into an upper and lower byte.
•
The lower value is calculated using Factor = 1.
•
The unsigned upper 2-byte value is calculated using Factor = 0.00390625 (= 1/256).
•
The unsigned upper 4-byte value is calculated using Factor = 0.0000152587890625 (= 1/65536).
•
The conversion of a 1-byte unsigned value from a value range 0...255 into 0...100 is calculated using
Factor = 0.00390625.
Other
Unlinked inputs are treated as if they did not exist.
