AC (Accumulator registers), L (Local memory) of PLC Devices can not use in MICRO/I.
- The value of High speed counter which is a double word value is divided into two, and is treated as WORD device in
MICRO/I.
The higher word is written by adding 0 to the lowest digit of the address, the lower word is written by adding 1 to the
lowest digit of the address.
