  1. MUST HAVE SHOULD HAVE COULD HAVE Module # 130

  2. Maintaining a Qi Cluster • Objectives • Know which files must be backed up • Know how to restore a system from scratch • Know what other routine tasks need to be done

  3. Maintenance list A • Do : • Calibrate the scale regularly • Make copies of the *.DMT files after calibration or editing • Replace battery every 3 yrs • Use an FTP utility to copy files out of the Qi • IE, FreeFTP or other • NOTE: copy only one file at a time • WARNING! Process must not be running !! • Class Exercise using a FTP util • Copy all files • Optional exercise – time permitting • Master Reset the QiMPACT • Hint: IP address and Subnet mask must be set first • Copy all DMT files back into QiMPACT • Cycle power

  4. Maintenance list B • The battery supplies power at all configuration data except: • Scale calibration data which stays with the board • The battery is situated inside the Power supply module • A capacitor will maintain power to the RAM for a few minutes allowing you to change the battery without losing the data • Ensure that all QiMPACT have the same version of firmware • (Web Pages): Maintenace > System Information • Recommend that all QiMPACT have cooling fans installed • Some earlier models shipped without • The analogue scale board must be the DMA version. • ControlNet EDS file versions • Ver 1.1 for QiMPACT only • Ver 1.2 for JagXterme only • Ver 1.3 for QiMPACT and jagXtreme • Profibus GSD file: • Qi.gsd

  5. Configuration Data backup and restore • PAC and general configuration are all stored in *.DMT files • These files can be copied out of and into the QiMPACT using FTP utility’s • Two important ones are: • JAGXAPC.DMT (All PAC configuration ) • JAGXCAL.DMT (All hardware calibration setup) • Should be done after any calibrations or significant editing of the Database • WARNING: • The operation can affect the QiMPACT. Do not attempt while the process is active or running! • Only copy ONE file at a time • A failed or spare QiMPACT can be restored by simply copying all *.DMT files back into the QiMPACT. • NOTE: channels will have to be licensed again if a different processor board is installed. If not SPILL ONLY algorithms will be used

  6. Other maintenance functions • Review the process parameters ie system performance • Average Spill and Flows.. Are they centralized within the limit • A change can mean something is wrong • A partially blocked pipe • Review the MaterialTransferProcess screen, are there any warnings (orange, red or yellows. • TIP: the Spill and Flow 50%, 75% and 100% limit status’s should all be green, they are not visible when OFF and this is a Warning or Error condition • Review Qi365 data. Look for step changes and error conditions

  7. Review Questions • Which version of Cnet EDS files will work with the QiMPACT? • How and what must we backup in case of a system crash or failure? • Can we do the above while the Qi is controlling a process
