Word/Bit Addresses Each word/bit address specifies a specific bit or word. The rightmost two digits of
the address specify bit 00 to 15 (or 00 if not required), and leftmost four digits
specify the word address.
Specify the the bit between 00 and 0F (00 to 15).
Set to 00 to specify word data.
Specify the address of the 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
in communications (see table on previous page). For example, the address for
word AR 13 is computed as follows:
First address for AR area: 048C
048C + 0D (13 in decimal): 0499
The word address for AR 13 would thus be 049900 (the memory area code
would specify this as a word) and the address of bit 12 in AR 13 would be
04990C.
The unit of access (bit or word) and the data code are specified as shown in the
following illustration.
Memory Area Codes Memory area codes are the following configuration of access sizes and area
codes.
00: Bit
10: Word
Access unit
Data code
00: CIO, LR, HR, or AR area
01: Timer or Counter area
02: Data Memory area
Bit
Number of Bytes A specific number of bytes is required for each element specified for either
MEMORY AREA READ or MEMORY AREA WRITE. This will vary depending on
the access unit of the memory area code, as indicated below.
Bit Access; 1 byte per element
Word Access; 2 bytes per element
Data Configuration The configuration of the various types of data that can be read or written is
shown below. The number of bytes required for each type of data is also given.
•
Flag or Bit Status (One Byte) 00: Bit is OFF (0)
01: Bit is ON (1)
