PlcConnectionInitFlags (ENUM) ¶ TYPE PlcConnectionInitFlags : InOut: Name Initial Comment DoDeviceLogin 16#1 This flag is no longer evaluated as the device login is mandatory for plcs with runtime versions >= 3.5.2 and it does not hurt for older runtimes. Further code assumes that this flag is set. DoApplicationLogin 16#2 DoApplicationLoginWithoutGuidsCheck 16#4 Very special mode where the application login will be done but the appconnection does not know the guids of the runtime. Due to this the appconnection will store the returned guids and do no check if the guids are valid. This can be used for example if a known address shall be monitored. PointerSize16Bit 16#8 The default pointer size is 32 bit. Alternative sizes can be set using the following two (of course only one of them) flags PointerSize64Bit 16#10 NoByteSupport 16#20 Special mode for devices not supporting byte access. Not yet implemented for the dataserver.

IDataSourceDriver5.ProcessDataServerRequest (METH) ¶ METHOD ProcessDataServerRequest : UDINT Generic method to pass a request from the data server to the PLC. The return value indicates, whether the processing was successful. The result (i.e. the number of rows) will be returned asynchronuously by method ProcessDataServerReply. InOut: Scope Name Type Comment Return ProcessDataServerRequest UDINT Input itfRequestParameter IRequestParameter The parameters for executing the request Output dwTransactionId DWORD Returns the ID of the transaction for the request
