Communications Commands
Section 6-2
Number of Writes Control
Uses 3 bytes of data from the specified start address as the Number of Writes
Control Area and writes data to the Data Carrier.
The number of writes for one command execution can be from 0 to 255.
Note
1.
Verification will not be performed if No Verification is set for writing.
2.
When using EEPROM (battery-free) Data Carriers, be sure the write area
is all on one page (refer to
page
59). If processing is performed for which
the write area extends across more than one page is performed for this
Data Carrier, The Data Carrier Address Error Flag (word (n + 8), bit 13) in
the Results Information will turn ON and the command will not be execut-
ed.
3.
Check the memory capacity of the Data Carriers before setting the Pro-
cessing Address and Number of Processing Bytes. If the Processing Ad-
dress and Number of Processing Bytes are not suitable for the Data
Carriers for which communications are being performed, the Data Carrier
Address Error Flag (word (n + 8), bit 13) will turn ON.
