• When the data in S1 or S2 is outside the range of 0 to 32,767, the result is a user program execution error.
• When the data specified by S1 is the same value as the data specified by S2 or a larger value, the result is a user program execution error.
For user program execution errors, see "User Program Execution Errors" on page 3-10.

Generates pseudorandom numbers.
When the input is on, a pseudorandom number is generated with the data specified by
S1 as the lower limit and the data specified by S2 as the upper limit, and that value is
stored in D1.
The result is stored to the destination designated by device D1.
