Square Root
This instruction performs a square root operation on the content value of device and stores the result to the
destination device .
It performs a square root operation on the content value of D0 and stores the result at D1 when X20=“ON”.
For the result, only the integer part will be taken, while the decimal part will be ignored; when any decimal is
ignored, M9021=“ON”.
The Zero Flag M9020=“ON” when the operation result is equal to “0”.
must be a positive; a negative will be determined an error operation by PLC and the M9067 will be set “ON”.
The 16-bit instruction, S = 0~32,767 The 32-bit instruction, S = 0~2,147,483,647
