SX2 ES2/EX2 SS2

SX2 ES2/EX2 SS2

: Lower bound of the random number S

: Upper bound of the random number D: Operation

Explanations:

1. The range of 16-bit operands S

≦K32,767; the range of 32-bit operands S

≦K2,147,483,647.

2. Entering S

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.

RAND D0 D10 D20
