SECTION 6
Controlling the ID Sensor Unit
Calculation Write
Reads the specified number of bytes from the specified start address, performs the specified
calculation with the data specified for the Command Option, and writes the result.
The calculation result is stored in the data storage area.
Up to 4 bytes (i.e., 2 words) can be specified for one command execution.
• If an addition results in an overflow or a subtraction results in an underflow, the Status Flag (CIO n+8, bit 04) will turn
ON and the number of writes data will not be changed.
• Verification will not be performed if No Verification is set for writing.
• Check the memory capacity of the RF Tag before setting the Processing Address and Number of Processing Bytes. If
the Processing Address and Number of Processing Bytes are not suitable for the RF Tag for which communications
are being performed, the RF Tag Address Error Flag (CIO n+8, bit 13) will turn ON.
