Parameter Declaration Data Type Memory Area DescriptionAL_INFO INPUT DWORD I, Q, M, D, L,constantInterrupt IDThis is transferred to the OB40 that will be startedon the DP master (variable OB40_POINT_ADDR).If you operate the intelligent slave with a remotemaster, you must evaluate the diagnostic frame onthe master.RET_VAL OUTPUT INT I, Q, M, D, L If an error occurs while the function is being exe-cuted, the return value contains an error code.BUSY OUTPUT BOOL I, Q, M, D, L BUSY = 1: The triggered hardware interrupt hasnot yet been acknowledged by the DP master.Value Description0000h The job was executed without errors.7000h First call with REQ = 0. No hardware interrupt request is active; BUSY has the value 0.7001h First call with REQ = 1. A hardware interrupt request has already been sent to the DP master; BUSYhas the value 1.7002h Interim call (REQ irrelevant): the triggered hardware interrupt has not yet been acknowledged by the DPmaster; BUSY has the value 1.8090h Start address of the address range in the transfer memory is incorrect.8091h Interrupt is blocked (block configured by user)8093h The parameters IOID and LADDR address a module that is not capable of a hardware interrupt request.80B5h Call in the DP master not permitted.80C3h The required resources (memory, etc.) are occupied at this time.80C5h Distributed I/O device is not available at this time (i.e. station failure).80C8h The function is not permitted in the current DP master operating mode.8xyyh General error informationÄ Chap. 4.2 ‘General and Specific Error Information RET_VAL’ page 6614.1.10 SFC 12 - D_ACT_DP - DP-Activating and Deactivating of DP slavesWith the SFC 12 D_ACT_DP, you can specifically deactivate and reactivate configuredDP slaves. In addition, you can determine whether each assigned DP slave is currentlyactivated or deactivated.The SFC 12 cannot be used on PROFIBUS PA field devices, which are connected by aDP/PA link to a DP master system.As long as any SFC 12 job is busy you cannot download a modified con-figuration from your PG to the CPU. The CPU rejects initiation of an SFC12 request when it receives the download of a modified configuration.RET_VAL (Return value)DescriptionVIPA SPEED7 Integrated StandardSystem Functions > SFC 12 - D_ACT_DP - DP-Activating and Deactivating of DP slavesHB00 | OPL_SP7 | Operation list | en | 18-30 653
