6.9.6 OB 86 - RACK_FLT - Slave Failure / RestartThe operating system of the CPU calls OB 86 whenever the failure of a slave is detected(both when entering and outgoing event).If OB 86 has not been programmed, the CPU changes to the STOPmode when this type of error is detected.The OB 86 may be delayed by means of the SFC 41 and re-enabled by the SFC 42.The following table describes the start information of the OB 86 with default names of thevariables and its data types:Variable Type DescriptionOB86_EV_CLASS BYTE Event class and identifiers:38h: outgoing event39h: incoming eventOB86_FLT_ID BYTE Error code:(possible values: C4h, C5h, C7h, C8h)OB86_PRIORITY BYTE Priority class:may be assigned via hardware configurationOB86_OB_NUMBR BYTE OB number (86)OB86_RESERVED_1 BYTE reservedOB86_RESERVED_2 BYTE reservedOB86_MDL_ADDR WORD Depends on the error codeOB86_RACKS_FLTD ARRAY (0 ... 31) OF BOOL Depends on the error codeOB86_DATE_TIME DATE_AND_TIME Date and time of day when the OB was calledInformation to access the local data can be found at the description of the OB 1.If you want to program OB 86 dependent on the possible error codes, we recommendthat you organize the local variables as follows:Variable TypeOB86_EV_CLASS BYTEOB86_FLT_ID BYTEOB86_PRIORITY BYTEOB86_OB_NUMBR BYTEOB86_RESERVED_1 BYTEDescriptionLocal dataOB 86 depending on errorcodesVIPA SPEED7Organization BlocksAsynchronous error Interrupts > OB 86 - RACK_FLT - Slave Failure / RestartHB00 | OPL_SP7 | Operation list | en | 18-3096
