Note
1.
If communications with the Data Carrier fail or an error occurs, communications will be aborted at that
point, the error flags in the Results Information (word (n + 8)) will turn ON accordingly, and the error
code will be placed in the Processing Results Monitor (word (n + 9)). The previous read data will not
be changed.
2.
If the Abort Bit is turned ON while waiting for a Data Carrier, communications will be aborted at that
point. The Results Information (word (n + 8)) will always be 0000 (hex) in this case.
3.
To confirm the execution results from the user program, use the ON status of the Normal End Flag or
Error End Flag in the Unit Status.
4.
Do not turn ON the Command Execution Bit during command execution (i.e., while the ID Busy Flag
is ON). It will be ignored.
