We completed the BRS image analysis software updates that had previously been unsuccessful (50178). The new version writes values to TwinCAT at a slightly different rate which is compensated for by changing the pulse check number from 10 to 20 in the following line in the BRS TwinCAT:

IF H1_ISI_GND_BRS_ETMX_PULSECHECK>=10

The last time we attempted the upgrade, TwinCAT threw the an error saying that "ProjectDefaults.opt could not be loaded (Reason: Root element is missing)". We found that this file existed and decided to just move it to another location with the hope that TwinCAT would recreated a non-corrupted version. This appears to have worked and TwinCAT began functioning correctly.

With this fixed the rest of the process was fairly straight forward and we were able to get both BRSs upgraded. To ensure that the new code is functioning as well as the previous version, we compared the online tilt subtraction to an optimal subtraction calculated with mccs2 (shown in the attachments). Both BRSs look like they're functioning perfectly.

Note: this upgrade did not alter the previous versions so, if needed, switching back to the old version consists of just running a different software
