Operands:
S: Source device D: Device for storing the result
Explanations:
1. See the specifications of each model for their range of use.
2. Flags: M1020 (zero flag); M1021 (borrow flag); M1067 (instruction operation error)
3. This instruction performs a square root operation on S and stores the result in D.
4. S can only be a positive value. If S is negative, PLC will regard it as an “instruction operation error” and will not
execute this instruction. M1067 and M1068 = On and D1067 records the error code 0E1B (hex).
5. The operation result D should be integer only, and the decimal will be left out. Borrow flag M1021 = On.
6. When the operation result D = 0, zero flag M1020 = On.
Program Example:
When X10 = On, the instruction performs a square root on D0 and stores the result in D12.
