08 Port 1 Protocol Macro Executing Flag (instruction
execution)
This flag is turned ON when a PMCR(––) instruction (se-
quence) is executed. The flag will remain OFF if execution
fails.
When the sequence is completed and receive data is writ-
ten, the flag is turned OFF after all the receive data has
been written to I/O memory.
This flag is turned OFF when the sequence is completed
(either when it is ended by End, or when it is ended by
Abort).
When the scan response notification method is set for the
sequence, first a check is made to see if the received data
has been written to I/O memory before the Protocol Macro
Executing Flag is turned OFF.

10 Port 1 Sequence END Completion Flag
This flag is turned ON when a sequence is completed for

mand.
Setting END when a sequence has ended normally and
setting ABORT when the sequence has ended abnormally
enables this flag to be used to determine whether or not
the sequence execution has ended normally.
