Value Description8090h The specified target address of the communication partners is not valid, e.g.n bad IOIDn bad base address existsn bad MPI-address (> 126)8092h Error in SD or RD, e.g.:n The amount of data received is too much for the buffer defined by RD.n RD has data type BOOL but the length of the received data is greater than one byte.8095h The block is already being processed on a priority class that has a lower priority.80A0h Error in received acknowledgment.80A1h Communication failures: SFC-call after an existing connection has been terminated.80B1h ANY-pointer error. The length of the data block that must be transferred is wrong.80B4h ANY-pointer data type error, or ARRAY of the specified data type is not permitted.80B6h The received acknowledgment contains an unknown error code.80BAh The answer of the communication partner does not fit into the communication telegram.80C0h The answer of the communication partner does not fit into the communication telegram.80C1h Lack of resources on the CPU where the SFC is being executed, e.g.:n the module is already executing the maximum number of different send operations.n connection resources may be occupied, e.g. by a receive operation.80C2h Temporary lack of resources for the communication partner, e.g.:n The communication partner is currently processing the maximum number of operations.n The required resources (memory, etc.) are already occupied.n Not enough memory (initiate compression).80C3h Error when establishing a connection, e.g.:n The local station is connected to the MPI sub-net.n You have addressed the local station on the MPI sub-net.n The communication partner cannot be contacted any longer.n Temporary lack of resources for the communication partner.14.1.51 SFC 67 - X_GET - Read dataThe SFC 67 X_GET can be used to read data from an external communication partnerthat is located outside the local station. No relevant SFC exists on the communicationpartner. The operation is started when input parameter REQ is set to 1. Thereafter thecall to the SFC 67 is repeated until the value of output parameter BUSY becomes 0.Output parameter RET_VAL contains the length of the received data block in bytes.The length of the receive buffer defined by parameter RD (in the receiving CPU) must beidentical or greater than the read buffer defined by parameter VAR_ADDR (for the com-munication partner) and the data types of RD and VAR_ADDR must be identical.DescriptionVIPA SPEED7Integrated StandardSystem Functions > SFC 67 - X_GET - Read dataHB00 | OPL_SP7 | Operation list | en | 18-30708
