		If error code 1, 2, 3, or 4 is stored, the Port 1 Protocol
		Macro Execution Error Flag (IR 20111) will be turned ON,
		the ERR/ALM indicator on the CPU Unit will flash, and a
		non-fatal error will occur.
		When an error occurs, the error code is held until the next
		sequence starts.
		The error must be cleared from a Programming Console or
		other Programming Device after the cause of the error has
		been eliminated.
	12 to 15	Port 2 Protocol Macro Error Code
		Same as IR 20408 to IR 20411, but works together with
		IR 20112.

		Reception matrix case numbers 0 to 15 (0 to F hex) are	status	matrix is
				received
		stored for which reception has been completed. The num-
		ber is cleared when the sequence execution starts.
		The Executed Reception Case No. is stored only when the
		reception matrix is set using the RECEIVE or SEND&RE-
		CEIVE command. If a reception matrix is not set, the case
		number will be set to 0 (cleared) when another command
		is executed.
	04 to 07	Port 1 Completed Step Number		When step
		Step numbers 0 to 15 (0 to F hex) are stored for the steps		is executed
		for which execution has been completed.
