T820 HANDBOOK4.2 AUTOMATIC BUILDAn automatically generated LIN Database does not result in a complete, usable control strategy, and is dependant onthe hardware configuration of the Instrument. However, it does provide the user with sufficient information, forming agood starting point for the user to begin building a more detailed control strategy.An instrument operating as a Control unit, can automatically generate a basic range of diagnostic function blocks toassist in identifying and monitoring the instrument and system, generating and configuring appropriate function blocksto replicate the hardware.The table below shows a list of diagnostic function blocks that are automatically generated as part of the automaticallycreated LIN Database, if a LIN Database is not loaded and the power is isolated, then re-applied.Block Type Block Name FunctionDB_DIAG DDIAG_nn Database diagnostics block. Shows actual and maximum resource levels of the LINDatabase by the current software. Displayed parameter values are only valid at runtime.EDB_DIAG EDIAG_nn External database diagnostics block. Shows connection information to one externaldatabase running in remote instruments and monitors the cached block update rate tuningalgorithm.EIO_DIAG EIODI_nn Ethernet I/O system diagnostic block. Shows the current state (Healthy/Unhealthy) of theexpected and actual I/O modules at each site. It can display a maximum of 16 I/O sites onone screen.ELINDIAG ELIND_nn ELIN diagnostics block. Statistics on the operation of the Ethernet Local InstrumentNetwork (ELIN).IDENTITY IDENT_nn IDENTITY diagnostics block. Identifies the instrument containing this function block.LIN_DEXT LDEXT_nn LIN High-level diagnostics extension block. Statistics on the operation of the LocalInstrument Network (LIN).OPT_DIAG ODIAG_nn Options/Licence Control System diagnostics block. Shows the user system attributes thatmay impose some limit of operation, or cause a licence violation alarm. The block is notessential to the LIN Database, and can be added while online.PNL_DIAG PNLDI_nn Panel diagnostic block. Shows information about the panel.SFC_DIAG SFCDI_nn Sequence diagnostics block. If SFC is enabled, this block shows actual and maximumresource levels of the sequence by the current software. It displays parameter values thatare only valid at runtime.TACTTUNE TTUNE_nn Tactician tuning block. System task monitoring in priority order.USERTASK UTASK_nn User Task diagnostic block. Control strategy task performance monitoring.Note. ‘nn’ denotes the numeric instance of that specific block type.Table 4.2 Automatically generated diagnostic function blocksChapter 4Page 4 - 2HA029131Issue 3 Feb 08
