Operands:
S: Source device D: Device for storing the result
Explanation:
1. This instruction performs a square root operation on S and stores the result in D.
2. S can only be a positive value. Performing a square root operation on a negative value will
result in an error and the instruction will not be executed. The error flag M1067 and M1068 =
ON and D1067 records error code H0E1B.
3. The operation result D should be integer only, and the decimal will be left out. When decimal is
left out, borrow flag M1021 = ON.
4. When the operation result D = 0, zero flag M1020 = ON.
Program Example:
When X20 = ON, square root of D0 will be stored in D12.
