it is possible to remove an oxide from BLX.
If the BLX system have been generated with a lot of differnet oxides the estimation takes a very long time and BLX often generate a warning saying that BLX have not been responding for X sec. of time (for instance: BLX have not been responding for 63 sec).
For a normal BLX system using LSF, SIM and ALM the main oxides that should be present is:
Other oxides can off cause be included in the configuration, but the more oxides thats included the more calculations BLX have to do for each estimation. So it is recommended to keep the included oxides to a minimum.
To remove an oxide:
FIRST - Do a full backup and ensure it is completed and saved in a seperate location. Put QCX in Maintenence mode OR you can follow the below instructions and then before saving - Halt BLX and then save.
Go to:
System and activate the Specific solution for Blx
(Image #1).
Go to the BLX configuration:
system --> Configuration --> configuration --> Blx --> Mill --> Dataitem
- Select the right solution (image #1)
- Right click on the oxide to be removed in the dataitem table and select delete - or just select the oxide and press Delete
- A progress Information window will open (it can take some time so just wait for it) and show the dependencies for the oxide.
- Scrool down in the progress information window to see all the dependicies (Image #2).
All the dependencies listed will have to be removed/deleted.
All TrendableOutputs including MgO have to be deleted. This is done by finding the right subsection, then selecting trendAbleOutput, find the row with the oxide to be removed and and then press "Delete" on the keyboard (image #3).
This needs to be done for all the trendableoutput listed in the progress window (image #1 & 2)
By following the listed dependencies in the Progress information window all the dependencies can be deleted one by one.
Finally the selected oxide can be deleted in the Dataitem table (Image #1).
After this close Workplace
Stop and Start Services
Start BlX and edited the HMI to remove the deleted/removed oxide.
Try to do a recalcuate Set Points to check that BLX is still working.
