2.3 Application Instructions
Processing details
Generates a random number between 0 and less than 32767, and stores the random number in
the device specified by (d).
Changes the random number sequence according to the content of the 16-bit binary data stored in
the device specified by (s).
Processing details
Saves data of the index register to the area specified by (d).
Reads the data, which has been saved to the area specified by (d)and later, into the index register.
Processing details
Saves the contents of the index register and long index register specified by (s) to the area
specified by (d).
Reads the data, which has been saved to the area specified by (d), into the index register and long
index register.
Processing details
Controls the output value depending on whether the specified 16-bit binary bit value is within the
upper and lower limits.
Controls the output value depending on whether the specified 32-bit binary bit value is within the
upper and lower limits.
Processing details
Controls the output value depending on whether the specified 16-bit binary bit value is within the
upper and lower limits of the dead band.
Controls the output value depending on whether the specified 32-bit binary bit value is within the
upper and lower limits of the dead band.
