Program Examples
Section 3-1
While the ID Sensor Unit is executing the command, the ID Busy flag (word
n+4 bit 00) is turned ON. When the Auto Write operation is complete, the ID
Busy flag turns OFF.
While the ID Sensor Unit is waiting for the Data Carrier to approach the
antenna, the Data Carrier waiting flag (word n+4 bit 01) is ON.
Although the ID Busy flag normally turns OFF upon completion of the com-
mand, if the command execution flag is ON at this time, the ID Busy flag will
stay ON. Therefore, design the program so that the command execution flag
will be turned OFF when the ID Busy flag turns ON, as in the example.
Program Example 3:
The Clear-all Command
Operation When the command execution input is ON, the number of words in the com-
mand (fixed to 3 words) and the beginning word where the command is stored
(DM 0600) are set using MOV, and the command execution flag (10000) is set
turned ON. IR (10904) keeps the status until the ID Sensor Unit begins exe-
cuting the command.
