Status References

Status references in the Remote I/O Scanner are assigned to %S, %SA, %SB, and %SC memory. These references have the same definitions as the status references for the Series 90±70 PLC, although not all are meaningful for a Remote I/O Scanner. They can be monitored using the reference tables function of Logicmaster 90 with the programmer communicating with the remote drop.

	Reference	Nickname	Definition
	%S0001	FST_SCN	Current sweep is the first sweep.
	%S0003	T_10MS	0.01 second timer contact.
	%S0004	T_100MS	0.1 second timer contact.
	%S0005	T_SEC	1.0 second timer contact.
	%S0006	T_MIN	1.0 minute timer contact.
	%S0007	ALW_ON	AlwaysON.
	%S0008	ALW_OFF	AlwaysOFF.
	%S0009	SY_FULL	Set when the Remote I/O Scanner's PLC Fault Table fills up. Cleared when an entry is re-
			moved from the PLC Fault Table and when the PLC Fault Table is cleared.
	%S0010	IO_FULL	Set when the Remote I/O Scanner'sI/OFault Table fills up. Cleared when an entry is re-
			moved from the I/O Fault Table and when the I/O Fault Table is cleared.
	%S0011	OVR_PRE	Set when an override exists in %I or memory.
	%SA0009	CFG_MM	Set when a configuration mismatch is detected during power±up or during a store of the
			configuration. Cleared by powering up the Remote I/O Scanner when no mismatches are
			present or during a store of configuration that matches hardware.
	%SA0010	HRD_CPU	Set when the diagnostics detects a problem with the Remote I/O Scanner hardware. Cleared
			by replacing the Remote I/O Scanner.
	%SA0012	LOS_RCK	Set when an expansion rack in the remote drop stops communicating with the communicat-
			ing with the Remote I/O Scanner. Cleared by fixing the problem and power cycling the rack.
	%SA0014	LOS_IOM	Set when an I/O module stops Remote I/O Scanner. Cleared by replacing the module and
			cycling power on the rack containing the module.
	%SA0015	LOS_SIO	Set when an option module stops communicating with the Remote I/O Scanner. Cleared by
			replacing the module and cycling power on the rack containing the module.
	%SA0017	ADD_RCK	Set when an expansion rack is added to the remote drop. Cleared by cycling power on the
			rack containing the module and when the con figuration matches the hardware after a store.
	%SA0019	ADD_IOM	Set when an I/O module is added to a rack. Cleared by cycling power on the rack containing
			the module and when the configuration matches the hardware after a store.
	%SA0020	ADD_SIO	Set when an option module is added to a rack. Cleared by cycling power on the rack contain-
			ing the module and when the configuration matches the hardware after a store.
	%SA0023	IOM_FLT	Set when an I/O module reports a circuit or module fault. Cleared by cycling power on the
			rack containing the module and when the config uration matches the hardware after a store.
	%SA0027	HRD_SIO	Set when a hardware failure is detected in an option module. Cleared by replacing the mod-
			ule and cycling power on the rack containing the module.
	%SA0032	SBUS_ER	Set when a bus error occurs on the VME bus backplane. Cleared by cycling power on rack 0.
	%SB0010	BAD_RAM	Set when the Remote I/O Scanner detects corrupted RAM memory at power±up. Cleared
			when the Remote I/O Scanner detects that RAM memory is valid at power±up.
	%SB0013	SFT_CPU	Set when the Remote I/O Scanner detects an unrecoverable error in the software. Cleared by
			cycling power to the Remote I/O Scanner.
	%SB0014	STOR_ER	Set when an error occurs during a programmer store operation. Cleared when a store opera-
			tion is completed successfully.
	%SB0017	SBUS_FL	Set when the Remote I/O Scanner fails to gain access to the bus. Cleared by cycling power on
			the rack 0.
	%SC0009	ANY_FLT	Set when any fault occurs. Cleared when both fault tables have no entries.
	%SC0010	SY_FLT	Set when any fault occurs that causes an entry to be placed in the Remote I/O Scanner's PLC
			Fault Table. Cleared when the PLC Fault Table has no entries.
	%SC0011	IO_FLT	Set when any fault occurs that causes an entry to be placed in the Remote I/O Scanner'sI/O
			Fault Table. Cleared when the I/O Fault Table has no entries.
	%SC0012	SY_PRES	Set as long as there is at least one entry in the Remote I/O Scanner's PLC fault table. Cleared
			when the PLC fault table has no entries.
	%SC0013	IO_PRES	Set as long as there is at least one entry in the Remote I/O Scanner's I/O fault table. Cleared
			when the I/O fault table has no entries.
	%SC0014	HRD_FLT	Set when a hardware fault occurs. Cleared when both fault tables have no entries.
	%SC0015	SFT_FLT	Set when a software fault occurs. Cleared when both fault tables have no entries
