InOut:

Name	Type	Initial	Comment
xHaModPrimary	BOOL	FALSE	State of the AC500 CPU. TRUE = PM acts as Primary. FALSE = PM acts as Secondary
xHaModCpuStop	BOOL	FALSE	IF TRUE -> Indicates the CPU in STOP mode
xHaModDataErr	BOOL	FALSE	IF TRUE -> HA data sync is in error state
wHaModDataErNo	WORD	0	HA data sync error code
diHaModTimersBaseTime	DINT	0	HA base time value for HA timers
xHaModErr	BOOL	FALSE	IF TRUE -> HA error state
dwHaModOwnIP	DWORD	0	Own IP address configured for sync link connection
dwHaModOtherIP	DWORD	0	Other PMs IP address configured for sync link connection
dwHaModServerAlive	DWORD	0	Life counter incremented by OPC server
wHaModEthLife	WORD	0	Ethernet Life Count
timHaModSyncTimeOut	TIME	TIME#20ms	LifeCom1 UDP synchronization timeout. May be changed by user based on Cycle time of HA Task
timCanTimeOut	TIME	TIME#100ms	LifeCom2 CAN timeout. May be changed by user based CAN and distance between 2 CPUs
uiHaModSyncArrayIndex	UINT	0	Synchronization Array index
stHAEthRecData	HaModEthFrameHeader		Received Ethernet Header
iTotalSyncData	UINT	0	Total sync data for the HA System
iNoOfEthFrames	INT	0	Number of Packages sent for for all Sync Data
xNoCiBus	BOOL	FALSE	No CI BUS configured, HA Standalone
timLifecom2Timeout	TIME	TIME#50ms	Time limit to check whether lifecom2 is received when configured via Modbus TCP
xEnableDualSync	BOOL	FALSE	Enable the dual sync mode, if configured ETH sync connection breaks, data sync will be switched to other onboard ETH port
timDualSyncPingTimeout	TIME	TIME#100ms	Dual sync ping timeout which defines the timeout to receive ping reply from another PLC
