^*1The Bit Register and the Register are the same device, but their bit write operation differs. Use either as needed.

^*2When bits are written, the Display reads the corresponding word address from the External Device, sets particular bits of that word address to ON, and then returns the resulting address to the External Device. Note that the data may not be written correctly if you write to the word address using the ladder program while the Display is reading data from, and writing data to, the External Device. To write bits to the write-only register, use a registering device. Writing bits to the write-only register will cause a communication error to appear when the readout command is executed.
