BSQR, BSQRP, BDSQR, BDSQRP
Function
The random number generation instruction generates random numbers conforming to a certain calculation formula. In the
calculation using the formula, the result of previous calculation is used as a coefficient.
The random series change instruction can change the random number generation pattern.
RND
Generates random number of from 0 to 32767, and stores at device designated by
SRND
Updates random number series according to the 16-bit BIN data being stored in device designated by
Operation Error
(1) There is no operation error in the RND(P) or SRND(P) instruction.
Program Example
(1) The following program stores random number at D100 when X10 is turned ON.
[Ladder Mode]
(2) The following program updates a random number series according to the contents of D0 when X10 is turned ON.
