2.5.3 Average Processing

1) The Cause of Average Processing
Average processing of noise or abnormal analog input is used to stabilize system control.
2) Kinds of Average Processing
There are kinds of average processing, which are time average and number average.
(1) Time Average Processing
a) Setting Range
G3F-AD4A(G3F-AD4B) : 96 to 12,000 (ms)
G4F-AD2A
b) On the time average processing, the number of average processing within the Set time is
determined according to the number of used channels .
Ex) Used channels : 4,
c) When Set time divided by(Number of used channel×Conversion speed) makes the residue occur,
the processing number will be [ { average processing number ÷ ( the number of used
channel × conversion speed) } + 1] by raising the residue.
Ex) Used channels: 4,
(2) Number Average Processing
a) Setting range
b) Number average processing period for writing digital value to the buffer memory is changed
according to the number of channels.
Ex) Used channels: 4, Average processing time: 50 count.

Processing number =
Set time : 120 ms
G3F-AD4A(G3F-AD4B) : 120÷(4×3) = 10 count
G4F-AD2A : 120÷(4×5) = 6 count
Set time : 150 ms
G3F-AD4A(G3F-AD4B) : 150÷(4×3) = 12 count + remain 6
G4F-AD2A : 150÷(4×5) = 7 count + remain 10
G3F - AD4A(G3F-AD4B, G4F-AD2A) : 2 to 4000 (count)
Processing time = Setting times×Number of used channels×Conversion speed
G3F - AD4A(G3F-AD4B) : 50×4×3 = 600 ms
