Commands and Responses for C200HX/HG/HE and CQM1H-series Section 6-6
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 PCs.
Memory area size varies depending on the PC model. For details, refer to the
operation manual of the specific PC that is being used.
Word/Bit Addresses 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:
First address for AR area; 048C (Hex)
048C + 0D (13 in BCD); 0499 (Hex)
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).
