The Function Block ARC_7F_SEND_SWAP is used to transmit data packages via the ARCNET Communication Module. The specified packages are stored in the transmit buffer which is selected by input PRIO. From there, the operating system hands over the data packages to the ARCNET Communication Module in order to transmit them to the target address specified at input NODE_ID. The transmit buffer size is determined using the PLC Configuration Parameters of PM5x1-ARCNET: Parameters of PM5x1-ARCNET (onboard ARCNET)ARCNET data exchange is automatically performed with receive acknowledgement. If TOUT = 0, no acknowledgement is expected. Output DONE indicates that the specified data package has been stored in the transmit buffer or that an error occurred during Function Block processing. If an error was detected during Function Block processing, the error is additionally indicated at the outputs ERR and ERNO. In case of an error, the data package has to be transmitted again.
Before the ARC_SEND Function Block can store data packages in the receive buffer, the setting “ARCNET data exchange” must have been selected in the Parameters of PM5x1-ARCNET: Parameters of PM5x1-ARCNET (onboard ARCNET)
