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.
4. D used in the 16-bit/32-bit instruction is a 32-bit register.
Program example 1:
When X10 = ON, the 3 consecutive devices (n = 3) from D0 will be summed up and the result will be
stored in (D11, D10)
