Cách sử dụng SCALE trong PLC CIMON?
Q: How to use SCALE in PLC
A: Use command SCL, SCLP, DSCL, DSCLP
SCL / DSCL S D T n
SCLP / DSCLP S D T n
S : Data value that you want to convert
D : Data value which will be converted and saved
T : The table that has Scale information
(Scale information must be saved at the 4 Word/Double word memory as format)
n : Number of data that will be converted
Converting 0~16000 value to -10~10
D0090 <= Minimum value (Example: 0)
D0091 <= Maximum value (Example: 16000)
D0092 <= Minimum scaled value (Example:-10)
D0093 <= Maximum scaled value (Example: 10)
As example, if D0020 is 8000, it will be converted to “0” as scale value and saved in D80.
