ParametersParameter Declaration Data type Memory block DescriptionRET_VAL OUTPUT TIME I, Q, M, D, L Parameter RET_VAL contains the system timethat was retrieved, range from 0 ... 231 -1ms.The SFC 64 does not return any error information.14.1.49 SFC 65 - X_SEND - Send dataThe SFC 65 X_SEND can be used to send data to an external communication partneroutside the local station. The communication partner receives the data by means of theSFC 66 X_RCV. Input parameter REQ_ID is used to identify the transmit data. This codeis transferred along with the transmit data and it can be analyzed by the communicationpartner to determine the origin of the data. The transfer is started when input parameterREQ is set to 1. The size of the transmit buffer that is defined by parameter SD (on thesending CPU) must be less than or equal to the size of the receive buffer (on the commu-nication partner) that was defined by means of parameter RD. In addition, the data typeof the transmit buffer and the receive buffer must be identical.Parameter Declaration Data type Memory block DescriptionREQ INPUT BOOL I, Q, M, D, L,constantcontrol parameter "request to activate", initiatesthe operationCONT INPUT BOOL I, Q, M, D, L,constantcontrol parameter "continue", defines whether theconnection to the communication partner is termi-nated or not when the operation has been com-pletedDEST_ID INPUT WORD I, Q, M, D, L,constantAddress parameter "destination ID". Contains theMPI-address of the communication partners.REQ_ID INPUT DWORD I, Q, M, D, L,constantOperation code identifying the data on the com-munication partner.SD INPUT ANY I, Q, M, D Reference to the send buffer. The following datatypes are possible: BOOL, BYTE, CHAR, WORD,INT, DWORD, DINT, REAL, DATE, TOD, TIME,S5_TIME, DATE_AND_TIME as well as arrays ofthe respective data types, with the exception ofBOOL.RET_VAL OUTPUT INT I, Q, M, D, L The return value contains an error code if an erroris detected when the function is being processed.BUSY OUTPUT BOOL I, Q, M, D, L BUSY = 1: the send operation has not yet beencompleted.BUSY = 0: the send operation has been com-pleted, or no send operation is active.Input parameter REQ_ID identifies the send data.Parameter REQ_ID is required by the receiver whenRET_VAL (Return value)DescriptionParametersREQ_IDVIPA SPEED7 Integrated StandardSystem Functions > SFC 65 - X_SEND - Send dataHB00 | OPL_SP7 | Operation list | en | 18-30 703
