: Accessible, : Not accessible, : No device
• Do not write data to the devices which cannot be written in the range of the special relays (M9000 to M9255)
and special registers (D9000 to D9255). For details on the special relays and special registers, refer to the
programming manual of ACPU.
• For L and S, perform accessing by specifying 'M' (For example, to access L100, specify M100.)
