Data Read/Write with ID Tag
4.1 Operating principle
A memory space of 240 bytes is assigned to an ID tag user. With this memory space, an 8-byte area (such as
00h-07h, 08h-0Fh
...
) is handled as one page.
The IDRW head can interact with the ID tag memory as described below.
➀
Data read
In this operation, data is read from the memory in ID tag. The operator can specify up to 16 arbitrary pages
as a read area.
➁
Data write
In this operation, data is written into the memory in ID tag. The operator can specify up to 16 arbitrary
pages as a write area. When intending to write same data to all the pages (same write), there is no limita-
tion about the number of target pages. It is also possible to write a given block of data in steps of bytes (byte
write).

Memory map (00h-EFh represent addresses)
* When the Model V700-HMD13 is used in the system, the data segments assigned to pages 13
through 30 have operational limitations. For further information, refer to "Limitations about Model
V700-HMD13" in the earlier part of this manual. The Model V700-HMD13A does not have such limi-
tations.
