PlcVarListMonitoring.OnExecuteMonitoringReply (METH) ¶ METHOD OnExecuteMonitoringReply : UDINT InOut: Scope Name Type Return OnExecuteMonitoringReply UDINT Input pduReply CHCProtocolDataUnit monProv IDataItemProvider2

PlcVarListMonitoring.OnMonitoringRequestSent (METH) ¶ METHOD OnMonitoringRequestSent : UDINT This method will be called while waiting for the answer of a previously sent monitoringrequest (SendMonitoringRequest). The method will return ERR_OK when the monitoring answer is available, ERR_PENDING while it is waiting for the answer and an error in the other cases. InOut: Scope Name Type Return OnMonitoringRequestSent UDINT Input channel IPlcServiceChannel Output pduReply CHCProtocolDataUnit

PlcVarListMonitoring.OnShuttingDown (METH) ¶ METHOD OnShuttingDown : UDINT This method will be called when the monitoring has to shutdown. The return value can be ERR_PENDING while some work is done. Afterwards it can return ERR_OK or an error when there was a problem. InOut: Scope Name Type Return OnShuttingDown UDINT Input channel IPlcServiceChannel
