Operands:

S: Source device n: Data length to be summed up

D: Device for storing the result

Explanations:

1.WSUM instruction sums up n devices starting from S and store the result in D.

2.If the specified source devices S are out of valid range, only the devices in valid range will be processed.

3.Valid range for n: 1~64. If the specified n value is out of the available range (1~64), PLC will take the upper (64) or lower (1) bound value as the set value.

Program example:

When X10 = ON, 3 consecutive devices (n = 3) from D0 will be summed up and the result will be stored in D10

X10		WSUM	D0	K3	D10
(D0+D1+D2)			D10
D0	K100
D1	K113		Result: D10	K338
D2	K125
