PLCHandler Programming Guide3 Configuration of the particular interfacesThe PLCHandler allows to communicate with a PLC via two different interfaces (ARTI or Gateway)and it makes possible a simulation of the PLC variables if no PLC is connected.See In the following how the PLCHandler must be configured in order to be able to communicate viathe particular interfaces.3.1 Simulationwill be supplied in a future version of the document3.2 ARTIwill be supplied in a future version of the document3.3 Gatewaywill be supplied in a future version of the document3.4 Simplified configuration with the CEasyPLCHandler ClassThe PLCHandler contains a derived class CEasyPLCHandler. This class encapsulates the mostimportant and popular communication channels and applies the appropriate correct settings.The following methods are available in addition to the PLCHandler methods:Method: long ::ConnectTcpipViaGateway(char *pszGatewayIP, char *pszPlcIP,char *pszProtocol = PLCC_DN_TCPIP_L2ROUTE,int bMotorola = 0, int bLoadSymbols = 1,unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT)This method can be used to set up a connection to a PLC via TCPIP and the Gateway on a Windowssystem. For this purpose only the IP address of the gateway as well as the IP address of the PLCmust be passed on. Default setting: Tcpip L2 Route Protocol.Method: long ::ConnectTcpipViaArti(char *pszPlcIP,char *pszProtocol = PLCC_DN_TCPIP_L2ROUTE,int bMotorola = 0, int bLoadSymbols = 1,unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);This method can be used to set up a connection to a PLC via TCPIP and ARTI. For this purpose onlythe IP address of the PLC must be passed on. Default setting: Tcpip L2 Route Protocol.Method: long ::ConnectRs232ViaArti(short sPort, unsigned long ulBaudrate,int bMotorola = 0, int bLoadSymbols = 1,unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);This method can be used to set up a connection to a PLC via ARTI and the serial interface. sPort = 1corresponds to COM1, etc.Method: long ::ConnectToSimulation(char *pszSdbFile, int bLoadSymbols = 1,unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);This method can be used to set up a connection to a simulation and to a SDB file. Only the name ofthe SDB file must be given. For this purpose also a complete path can be specified.Return value: These methods return same error values like the ::Connect() method. 3S - Smart Software Solutions GmbHPLCHandler Programmming Guide.doc Page 10 of 17
