4.7 Hardware and diagnostic interrupt4.7.1 Hardware interruptn Hardware interrupt data of System SLIO modules with interrupt capability were auto-matically sent by a diagnostics message if the interrupt is activated by parametriza-tion at the corresponding module respectively at the System SLIO PROFINET IOdevice.n On an hardware interrupt your master system jumps into an interrupt routine. Thereyou can read the hardware interrupt data by means of the block SFB 54 - RALARM.Hardware interrupt dataByte Description Example Content0..1 AlarmNotification (1: High, 2: Low) 0002h PROFINET interrupt data2..3 BlockLength 001Eh4..5 Version High/Low 0100h6..7 AlarmType (1: Diagnostics, 2: Process, 3: Pull) 0002h8..11 API 0000h, 0000h12..13 Slot 0003h14..15 Subslot 0001h16..19 ModuleIdentNumber 0006h, 1F41h20..23 SubmoduleIdentNumber 0000h, 0001h24..25 DiagnosticsState(PROFINET specific IEC 61158-6-10)0005h26..27 UserStructureIdentifier0000h ... 7FFFh: UserSpecifiedDiagnostics1000h: Hardware interrupt (VIPA specific)8002h: ExtChannelDiag1000h Hardware interrupt(VIPA specific)28..47 VIPA specific: Hardware interrupt data … Hardware interrupt data (seemodule description)4.7.2 Diagnostic interruptn Diagnostics interrupt data of System SLIO modules with interrupt capability wereautomatically sent by a diagnostics message if the interrupt is activated by parametri-zation at the corresponding module respectively at the System SLIO PROFINET IOdevice.n On an diagnostics interrupt your master system jumps into an interrupt routine. Thereyou can read the diagnostics interrupt data by means of the block SFB 54 - RALARM.n The interrupt behavior and the structure of the diagnostics data may be preset by theparametrization of the System SLIO PROFINET IO device. Among other you have thechoice between the following diagnostics data:– UserSpecifiedDiagnosticsHere all the diagnostics data can be accessed.– ExtendedChannelDiagnostics (channel-specific)Here record set 0 of the diagnostics data (4byte) may be accessed. Additionaldiagnostics data must explicit be requested.VIPA System SLIODeploymentHardware and diagnostic interrupt > Diagnostic interruptHB300 | IM | 053-1PN00 | en | 19-0864
