GetPlcIdent (FUN) ¶ FUNCTION GetPlcIdent : PLC_IDENT Returns the identification of the PLC, independent from active or passive state. InOut: Scope Name Type Return GetPlcIdent PLC_IDENT
GetRedundancyState (FUN) ¶ FUNCTION GetRedundancyState : BOOL Get current redundancy state information InOut: Scope Name Type Comment Return GetRedundancyState BOOL Input pState POINTER TO RedundancyState Redundancy state information
GetSyncInformation (FUN) ¶ FUNCTION GetSyncInformation : RTS_IEC_RESULT Fills structure SYNC_INFO with information about the redundancy synchronizsation status. InOut: Scope Name Type Return GetSyncInformation RTS_IEC_RESULT Input pSyncInfo POINTER TO SYNC_INFO
IsAddressInArea (FUN) ¶ FUNCTION IsAddressInArea : BOOL It checks if a generic memory address belongs to a registered memory area. InOut: Scope Name Type Comment Return IsAddressInArea BOOL Input pAddress POINTER TO BYTE Address to check Output eType AREA_TYPE Redundancy area type where the address belong to pArea POINTER TO BYTE Start address of area udiSize UDINT Size of area
RedundancySynchronizeData (FUN) ¶ FUNCTION RedundancySynchronizeData : BOOL Synchronze global data once. This includes the areas registered in redundancy. Can be called from active or standby controller. InOut: Scope Name Type Return RedundancySynchronizeData BOOL
SwitchToActive (FUN) ¶ FUNCTION SwitchToActive : BOOL Switches a plc to redundancy state RS_CYCLE_ACTIVE. Can be called in state RS_SIMULATION and RS_CYCLE_STANDBY. In state RS_SIMULATION, plc will become RS_CYCLE_ACTIVE (if second plc is running) or RS_CYCLE_STANDALONE (if second plc is not running). In state RS_CYCLE_STANDBY, plc will become RS_CYCLE_ACTIVE. State change is not performed immediately. A commend send to other plc in next StartCycle or EndCycle. InOut: Scope Name Type Return SwitchToActive BOOL
SwitchToSimulation (FUN) ¶ FUNCTION SwitchToSimulation : BOOL Switches a plc to redundancy state RS_SIMULATION. Can be called in state RS_CYCLE_STANDBY, RS_CYCLE_ACTIVE and RS_CYCLE_STANDALONE InOut: Scope Name Type Return SwitchToSimulation BOOL
SwitchToStandalone (FUN) ¶ FUNCTION SwitchToStandalone : BOOL Switches a plc to redundancy state RS_CYCLE_STANDALONE. Can be called in state RS_SIMULATION_START and RS_CYCLE_STANDBY. In state RS_SIMULATION_START, if application is not loaded: state is set and application is loaded and started. In state RS_CYCLE_STANDBY, with next StartCycle or EndCycle, command is sent to other PLC to switch to RS_SIMULATION. Then, own state is changed. InOut: Scope Name Type Return SwitchToStandalone BOOL
SwitchToStandby (FUN) ¶ FUNCTION SwitchToStandby : BOOL Switches a plc in redundancy state RS_CYCLE_ACTIVE to RS_CYCLE_STANDBY InOut: Scope Name Type Return SwitchToStandby BOOL
Synchronize (FUN) ¶ FUNCTION Synchronize : BOOL Synchronizes a plc in redundancy state RS_START, RS_BOOTUP_ERROR, RS_SYNCHRO_ERROR, RS_CYCLE_ERROR, RS_CYCLE_STANDALONE, RS_SIMULATION or RS_SIMULATION_START. Please note that the current application is stopped and unloaded before trying to sync with the other controller. In standlone mode, value of xReadyForSync of structure SYNC_INFO may be checked before calling this function. InOut: Scope Name Type Return Synchronize BOOL
