Data
Note The meanings of the memory area codes for the Expansion DM area are
shown in the following table. Only the current bank (98) or bank 0 (90) can be
specified for CQM1H-series PLCs.
Memory area size varies depending on the PLC model. For details, refer to
the operation manual of the specific PLC that is being used.
Each word/bit address specifies a specific bit or word.
To obtain the corresponding address of the desired word or bit, add the data
area word address (hexadecimal) to the first address of the range of
addresses used for that data area in communications. For example, the
address for word AR 13 is computed as follows:
The word address for AR 13 would be 04990C (Hex) (the memory area code
would specify this as a word) and the address of bit 12 (C Hex) in AR 13
would be 04990C (Hex).
The unit of access (bit or word) and the data code are specified as shown in
the following illustration.
The number of bytes of read or write data per element is as follows depending
on the access unit.
EM 0000 to EM 6143
