RDT_Server (FB) ¶ FUNCTION_BLOCK RDT_Server EXTENDS RDT_Base IMPLEMENTS IRdtProtServer Server FB that encapsulates NBS.TCP activities in Redundancy Data Transfer Sets up a server over the ip and port specified in “ipAddress” and “uiPort” in “Initialize” method. A server can handle several connections. The output “itfServer” of this function block can be used to establish a connection via |TCP_Connection| .

RDT_Server.FB_exit (METH) ¶ METHOD FB_exit : BOOL FB_Exit must be implemented explicitly. If there is an implementation, then the method is called before the controller removes the code of the function block instance (implicit call). The return value is not evaluated. InOut: Scope Name Type Comment Return FB_Exit BOOL Input bInCopyCode BOOL TRUE: the exit method is called in order to leave the instance which will be copied afterwards (online change).
