System Setup, Auxiliary Area Allocations, and Built-in I/O Allocations				Appendix C
Address	Bits	Name	Function	Controlled by
A500	14	Error Log Pointer Reset	The error log pointer in A408 is reset to 0000 hex and Memory Not	User
		and Memory Not Held	Held Flag (A404.14) is turned OFF when this bit is turned ON.
		Flag OFF Bit
A400	00 to 15	Error code	When a non-fatal error (user-defined FAL(006) or system error) or a	Module
			fatal error (user-defined FALS(007) or system error) occurs, the hexa-
			decimal error code is written to this word.
FAL/FALS Errors
Address	Bits	Name	Function	Controlled by
A401	06	FALS Error Flag	Turns ON when a non-fatal error is generated by the FALS(006)	Module
		(fatal error)	instruction. The FQM1 will stop operating.
A402	15	FAL Error Flag	Turns ON when a non-fatal error is generated by executing FAL(006).
		(non-fatal error)	The FQM1 will continue operating.
Memory Errors
Address	Bits	Name	Function	Controlled by
A401	15	Memory Error Flag (fatal	Turns ON when there is an error in the memory. FQM1 operation will	Module
		error)	stop and the ERR indicators on the front of the Modules will light.
A403	00	UM Error Flag	Turns ON when there is an error in the user memory.
	04	System Setup Error	Turns ON when there is an error in the System Setup in the Coordina-
		Flag	tor Module or Motion Control Module.
	10	Flash Memory Error	Turns ON when the flash memory is physically destroyed.
		Flag
	13	Analog Offset/Gain	Turns ON when there is an error in the analog I/O offset/gain adjust-
		Error Flag	ment value in flash memory.
	14	Flash Memory DM	Turns ON when there is an error in the DM Area data backed up in
		Checksum Error Flag	flash memory in the Coordinator Module.
A404	14	Memory Not Held Flag	Turns ON when corruption is found in the check performed after turn-
			ing ON power in the areas backed up during power interruptions (DM
			Area (Coordinator Module only) and Error Log Area).
System Setup
Address	Bits	Name	Function	Controlled by
A402	10	System Setup Error	Turns ON when there is a setting error in the System Setup.	Module
		Flag
A409	00 to 15	System Setup Error	When there is a setting error in the System Setup, the location of that
		Location	error is written to A409 in 4-digit hexadecimal.
I/O Errors
Address	Bits	Name	Function	Controlled by
A401	10	I/O Setting Error Flag	Turns ON when more than four Motion Control Modules are connected	Module
			to the Coordinator Module.
Module Errors
Address	Bits	Name	Function	Controlled by
A402	05	Motion Control Module	Turns ON in the Coordinator Module when a system error, such as a	Module
		Monitoring Error Flag	WDT error, occurs in any of the Motion Control Modules.
		(Coordinator Module
		only)
	13	Coordinator Module	Turns ON in the Motion Control Modules when a WDT error occurs in
		WDT Error Flag (Motion	the Coordinator Module.
		Control Modules only)
	14	Coordinator Module	Turns ON in the Motion Control Modules when a fatal error occurs in
		Fatal Error Flag (Motion	the Coordinator Module.
		Control Modules only)
