UDPDriver.ClosePort (METH) ¶ METHOD ClosePort : SysTypes.RTS_IEC_RESULT Close the udp port InOut: Scope Name Type Comment Return ClosePort SysTypes.RTS_IEC_RESULT Input pPort POINTER TO Port Port to close Output eLogCode ErrorCode

IBusSpecificDataHandler.SyncdWriterSize (PROP) ¶ PROPERTY SyncdWriterSize : UDINT Property of type ‘UDINT’ to save the size of the writer buffer which is set by the standard RTS. This size is used to synchronize with the buffer size of the F-SPS because there is no writer’s interface yet to get the size
