Control Bits, Flags, and Status Information
Word Bits
IR 207 00 Port 1 Restart Bit
The communications port will be restarted when this bit is
turned ON by the user.
01 Port 2 Restart Bit
Same as IR 20700.
02 Port 1 Continuous Trace Start/Stop Bit
The CX-Protocol will start a continuous trace when the bit is
turned ON. The trace is ended when the bit is turned OFF.
The CPU Unit will manipulate the Shot Trace Bit and Contin-
uous Trace Bit when trace operations are performed from
the CX-Protocol. Do not manipulate these bits directly from
a ladder diagram.
03 Port 2 Continuous Trace Start/Stop Bit
Same as IR 20702.
04 Port 1 Shot Trace Start/Stop Bit
The CX-Protocol will start a one-shot trace when the bit is
turned ON. The trace is ended when the bit is turned OFF.
The Serial Communications Board will be cleared when the
trace buffer becomes full.
The CPU Unit will manipulate the Shot Trace Bit and Contin-
uous Trace Bit when trace operations are performed from
the CX-Protocol. Do not manipulate these bits directly from
a ladder diagram.
05 Port 2 Shot Trace Start/Stop Bit
Same as IR 20704.
08 Port 1 Protocol Macro Executing Flag (instruction execu-
tion)
This flag is turned ON when a PMCR(––) instruction
(sequence) is executed. The flag will remain OFF if execu-
tion 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.
09 Port 1 Transfer Step Error Processing Flag
This flag is turned ON when a step has ended abnormally. It
is turned OFF if the step ends normally as a result of a retry.
1: Step ended abnormally
0: Step ended normally
10 Port 1 Sequence END Completion Flag
This flag is turned ON when a sequence is completed for
the next process or for an error process with an END com-
mand.
Setting END when a sequence has ended normally and set-
ting ABORT when the sequence has ended abnormally
enables this flag to be used to determine whether or not the
sequence execution has ended normally.
1: Sequence ended
0: Sequence not ended
