(Write location area for each ID number)
Data write areas can be assigned as follows by assigning "+02 to +32" to the "write header
address" (A). If there are 10 BL Series or SR Series devices connected, the following read data
will be divided into 10 parts in and saved in 10 separate write areas. (This is the case if each ID
number has a distinct data write header address).
Up to 255 digits worth of data can be saved in this data area.
BL Series devices can only store up to 96 digits worth of data (when using BL-210RK), but
SR Series devices can store 2D code data far more than 255 digits (up to 7089 digits: QR
code).
However, note that when using a PLC link, data over 255 digits cannot be stored into a
PLC.
Header address = 100, 3 devices connected (ID numbers 1, 2 and 3)
