Auxiliary Area Allocations				Appendix D
Address	Bits		Name	Function
A403	00	UM Error Flag		Turns ON when there is an error in the user memory.
	04	System Setup Error Flag		Turns ON when there is an error in the System Setup in the Coor-
				dinator Module or Motion Control Module.
	10	Flash Memory Error Flag		Turns ON when the flash memory is physically destroyed.
	13	Analog Offset/Gain Error Flag		Turns ON when there is an error in the analog I/O offset/gain
				adjustment value in flash memory.
	14	Flash Memory DM Checksum Error Flag		Turns ON when there is an error in the DM Area data backed up
		(Coordinator Module only)		in flash memory in the Coordinator Module.
A404	05	Constant Cycle Time Exceeded Flag		Turns ON when the actual cycle time exceeds the specified con-
				stant (minimum) cycle time.
	06	Sync Cycle Time Too Long Flag		Turns ON when one of the Modules exceeds the specified sync
				cycle time. (Coordinator Module only)
	14	Memory Not Held Flag		Turns ON when corruption is found in the check performed after
				turning ON power in the areas backed up during power interrup-
				tions (DM Area (Coordinator Module only) and Error Log Area).
A405	11	No END Error Flag		ON when there isn’t an END(001) instruction in each program
				within a task.
	12	Task Error Flag		ON when a task error has occurred. The following conditions gen-
				erate a task error.
				There isn’t a program allocated to the task.
	13	Differentiation Overflow Error Flag		The allowed value for Differentiation Flags which correspond to
				differentiation instructions has been exceeded.
	14	Illegal Instruction Error Flag		ON when a program that cannot be executed has been stored.
	15	UM Overflow Error Flag		ON when the last address in UM (User Memory) has been
				exceeded.
A408	00 to 15	Error Log Pointer		When an error occurs, the Error Log Pointer (binary) is incre-
				mented by 1 to indicate the location where the next error will be
				recorded as an offset from the beginning of the Error Log Area
				(A100 to A199).
A409	00 to 15	System Setup Error Location		When there is a setting error in the System Setup, the location of
				that error is written to A409 in 4-digit hexadecimal.
A410	02	RS-232C	Parity Error Flag	These error flags turn ON when an error has occurred at the RS-
		Port		232C port.
	03		Framing Error Flag
		Error
	04	Flags	Overrun Error Flag
	05		Timeout Error Flag
	08	RS-232C Port Communications Error Flag		Turns ON when a communications error has occurred at the RS-
				232C port.
	09	RS-232C Port Send Ready Flag (no-protocol		Turns ON when the RS-232C port is ready to send data in no-pro-
		mode)		tocol mode.
	10	RS-232C Port Reception Completed Flag (no-		Turns ON when the RS-232C port has completed the reception in
		protocol mode)		no-protocol mode.
	11	RS-232C Port Reception Overflow Flag (no-pro-		Turns ON when a data overflow occurred during reception
		tocol mode)		through the RS-232C port in no-protocol mode.
	15	RS-232C Port Settings Changing Flag		Turns ON while the RS-232C port’s communications settings are
				being changed.
A411	00 to 15	RS-232C Port Reception Counter (no-protocol		Indicates (in binary) the number of bytes of data received when
		mode)		the RS-232C port is in no-protocol mode.
A412	02	Periph-	Parity Error Flag	These error flags turn ON when an error has occurred at the
		eral Port		peripheral port.
	03		Framing Error Flag
		Error
	04	Flags	Overrun Error Flag
	05		Timeout Error Flag
	08	Peripheral Port Communications Error Flag		Turns ON when a communications error has occurred at the
				peripheral port.
	15	Peripheral Port Settings Changing Flag		Turns ON while the peripheral port’s communications settings are
				being changed.
