Module # 130
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
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
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
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
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
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
