Operands:
S 1 : Lower bound of the random number S 2 : Upper bound of the random number D: Operation
result
Explanations:
1. The range of 16-bit operands S 1 , S 2 : K0≦S 1 , S 2 ≦K32,767; the range of 32-bit operands S 1 ,
S 2 : K0≦S 1 , S 2 ≦K2,147,483,647.
2. Entering S 1 > S 2 will result in operation error. The instruction will not be executed at this time,
M1067, M1068 = ON and D1067 records the error code 0E1A (HEX)
Program Example:
When X10 = ON, RAND will produce the random number between the lower bound D0 and upper
bound D10 and store the result in D20.
