Communications Commands
Section 6-2
Copy (Double-head Unit ID
Sensor Units Only)
This command is supported by Double-head ID Sensor Units only. Data is
read from the Data Carrier for one R/W Head and written to the memory of a
Data Carrier in the communications area for the other R/W Head.
Writing to the second Data Carrier is always performed with a trigger.
Note
1.
If the Command Execution Bit is turned ON in the Unit Controls for Head
1, data will be read from the Data Carrier for Head 1 and written to the Data
Carrier for Head 2.
2.
If the Command Execution Bit is turned ON in the Unit Controls for Head
2, data will be read from the Data Carrier for Head 2 and written to the Data
Carrier for Head 1.
3.
The Communications Specification for the Head that writes data will al-
ways be a trigger regardless of the specified communications method.
4.
The Status Flag (word (n + 8), bit 04) in the Results Information will turn
ON if an error occurs in the Head that writes data.
5.
Confirm that the Head that writes data is not communicating before turning
ON the Command Execution Bit. If the Head that writes data is communi-
cating, the Status Flag (word (n + 8), bit 04) in the Results Information will
turn ON.
6.
Confirm the capacity of both the Data Carrier being read and the one being
written before using this command. If the Processing Address and Number
of Processing Bytes for the Head that write data are not suitable for the
Data Carrier being communicated with, the Status Flag (word (n + 8), bit
04) in the Results Information will turn ON.
