IR 201	00 to 03	Port 1 Error Code (Transmission Error Status)		Transmis-	When error	Start of
		When an error occurs during transmissions for a protocol		sion error	occurs	sequence
		macro, an error code will be output to these bits.
		0: Normal operation 1: Parity error	2: Framing error
		Error codes 3 to 7 are not possible for protocol macros.
		These error codes are the same regardless of the serial
		communications mode.
		IR 20104 will also turn ON except when the error code
		contains all zeros. SEND&RECEIVE retry processing will
		be performed for any error.
		If communications are recovered through protocol macro
		retry processing, the error code will be cleared, but will be
		maintained even if a different error occurs during the retry.
	04	Port 1 Communications Error Flag
		This flag turns ON when an error occurs in the
		communications path between the communications port
		and the external device or when communications
		parameters are not set correctly.
		The operation of this flag is the same regardless of the
		serial communications mode.
		Details on the error are output as an error code to
		IR 20100 to IR 20103.
	07	Port 1 Sequence Abort Completion Flag		Sequence	When
		This flag turns ON when a sequence has been aborted due		status	sequence is
		to ABORT in the next process or in the error process. It will			aborted
		be OFF if an abort has not occurred.
	08 to 11	Port 2 Error Code (Transmission Error Status)		Transmis-	When error
		Same as bits IR 20100 to IR 20103, but works together		sion error	occurs
		with IR 20112.
	12	Port 2 Communications Error Flag
		Same as bits IR 2014, but works together with IR 20108 to
		IR 20111.
	15	Port 2 Sequence Abort Completion Flag		Sequence	When

					refreshed
		The present value N varies according to the method used
		to initialize the value. For resets, the variable N is set to 0
		when the step is started, and the step is executed accord-
		ing to the set number of times. For holds, the variable N for
		the present value is held when the step is started, and the
		step is executed according to the set number of times.
		If the Repeat Counter Setting Value is set to read word
		R ( ), and 0 is read, then 0 will be stored and this step will
		be skipped (the next process setting will be ignored), and
		the sequence will move to the next step (+ 1). For details,
		refer to the CX-Protocol Operation Manual (W344).
IR 203	00 to 07	Port 2 Repeat Counter PV (00 to FF hexadecimal)
		Same as IR 20200 to IR 20207.
