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.
