IRMPService.Receive (METH) ¶ METHOD Receive : UDINT This method is called by each module that is able to receive a message it takes the oldest received message for uiReceiverID and acknowledges it. Returns 16#FFFFFFFF if there is no message waiting for the receiver. Returns 16#FFFFFFFE if there is at least one message waiting for the receiver, if the oldest message is currently locked by a different task. In all other cases, the communication address of the sender is returned. A possible call semantic could be: udiRec := Environment^.rmps.Receive(uiReceiverModuleID:=UDINT_TO_UINT(ComAddress AND 16#FFFF), pmd:=ADR(mdData)); Where udiRec returns the address of the module/communicator from which the message was received. Accesing this function was done using the environemin any module implementing IModule . InOut: Scope Name Type Comment Return Receive UDINT Input uiReceiverModuleID UINT The (local) address of the receiver, which equals the first 16bit of the ComAddress (see AND 16#FFFF) pmd POINTER TO ARRAY [0..63] OF BYTE The message data buffer to write to

IRmpService3.GetComFBForComAddress (METH) ¶ METHOD GetComFBForComAddress : IRMPFBCommunication This functions returns the communication FB used to communicate to or from a given Module ComAddress of a Module. ..note: If communication FBs are not used for communication this function will always return 0! ..return: If FB communication was used and a FB communicating to or from the given ComAddress exists the correspnding FB/Interface is returned If no communication FB is available 0 is reutnred. InOut: Scope Name Type Comment Return GetComFBForComAddress IRMPFBCommunication Input udiModuleComAddress UDINT The ComAddress of the Module for which the CommunicationFB shall be received
