Note 1. Special remote I/O outputs and inputs are paired. When using special remote I/O, be sure to
set them together.
Note 2. Special remote I/O objects do not conform to the AC/DC drive profile, but are specially set for
this product.
Note 3. The 16-bit data (register number and register data) is set using two words for each setting.
Note 4. Be careful of the order of the leftmost and rightmost bytes of the 16-bit data. The order is re-
versed from that of basic and standard remote I/O.
Note 5. For details on special remote I/O operation, refer to 5-4 Special Remote I/O.
