Input a filter on the analog input to reduce instability

Example, S7-1200, SCL language, 100 ms cycle execution:

where:

#i_Input - analog input

real_Input - analog input converted from word to real number,

fil_Input - filtred analog input,

i_Filter - filter coeficient (0 - no filtration, 1 - no measuring),

prev_Input - filtred input from previous cycle.

Have a nice day!

Attached is SCL source for a simple implementation of a Median Filter to process raw analog data integer values.  It is useful for eliminating noise 'flyers' in your signal data.  This filter takes the last eleven data values, puts them in numeric order least to greatest, then returns the value that is in the sixth position (middle) of the set.  You may increase the size of the data set for more aggressive filtering, but the trade off will be execution time and storage space.

Hope this may be useful for someone.  It solved a problem reading a noisy laser input for me.

Please can you send me this code too?

I have TIA V14, PLC S7-1200. I have very "jumpy" concentration detector and i need reduce it. 

Thank you very much

 The code is in the previous post as an attachment, and you can download from there.
