1. Output word: An I/O allocation command (C
jjj
) is set to specify the loop
and the items to be set and monitored.
2. Input word: The I/O allocation command set in the output word will be set by
the system as a “Command Acknowledged Flag” to indicate that the com-
mand has been acknowledged.
3. Output word: The write data for the I/O allocation command set in 1. is set.
4. Input word: After the data specified in 3. has been set, the data specified to
be monitored in 1. will be set by the system. This also functions as a “Write
Completed Flag” to indicate that the write operation has been completed.
