: upper limit for the random numbers D : Random
number result
Description:
1. The range of 16-bit operands S
1
, S
2
is: K0
≦
S
1
, S

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

is: K0
≦
S

≦
K2,147,483,647.
2. If S
1
> S
2
, the ELC will produce an operand error and M1067 and M1068=ON, and error code
0E1A(HEX) will be recorded in D1067.
Program Example:
When X0=ON, the random number produced between lower limit D0 and upper limit D10 will be
saved in D20.
