API Instruction code
1511 D SQR
Device X Y M
 
S
 
D
Symbol:
Explanation:
1. The square root of the value in the device specified by S is calculated, and the result is stored
in the device specified by D.
2. The operation result stored in D is an integer. If the floating-point number is rounded down to
the nearest whole digit, SM601 is ON.
3. If the operation result stored in D is 0, SM600 is ON.
Example:
When X0.0 is ON, the square root of the value in D0 is calculated, and the result is stored in D10.
Additional remark:
1. The value in the device specified by S only can be a positive value. If the value in the device
specified by S is a negative value, the operation error occurs, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#2003.
