7.7.2 Device specification ranges
The following is the device and device number range that can be used in the access of device
memory.
Each device is composed of five characters.
Device (1 character, 2 characters with timer and counter) + device number (4 characters, 2
characters with timer and counter) = 5 characters.
1 ) Bit devices
In FX series, the timer coil (TC) and counter coil (CC) are not supported.
2 ) Word devices
* Only CN000 to CN199 can be used.
(C200 to C255 of 32 bit counter or high speed counter cannot be used.)

Notes
1 ) When using bit devices specified in word units (WR, WW, WT), the number of the
head device must be a multiple of 8 (or if an octal device end in 0) e.g. X30, M24.
2 ) The special auxiliary relays (M8000 to M8255) and special data registers (D8000
to D8255) can be read only, write only, and received for system use.
If an attempt is made to write outside the write enable range, an error may occur in
the programmable controller. Accordingly, for details of special auxiliary relays and
special data registers, see the programmable controller manual.
