Beckhoff end X HEPI pump controller updated to match end Y
After Filiberto made the hardware changes to make the end X Beckhoff HEPI pump controller match the end Y Beckhoff HEPI pump controller, I went in and updated the software.

I installed Git and Visual Studio 2019, uninstalled Visual Studio 2017 (I needed the disk space) and updated the version of TwinCAT 3 to match that at end Y. I checked the code out of Git, and was able to cut, copy and paste the terminals in the IO tree to match the new configuration without losing any variable links. It is now running the code at commit c5b7d9505806fc91ef30caae79ca4e95c4f0c216 from https://git.ligo.org/cds/ifo/beckhoff/hepi-pump-ctrl/h1-hepi-pump-ctrl-ex.

Summary of harware configuration at EX:

  1. Unused terminals (EK1101 coupler, EL3602-0010, and EL2624) were removed.
  2. The Beckhoff electronics in the mechanical room were removed from the floor and racked on the open frame rack.
  3. A delta din rail power supply was installed to power both the mechanical and LVEA electronics.
  4. The LVEA chassis was installed in the half-rack between BSC9 and BSC5. This required two DB9 cables (MF, 15ft) to extend the signals from the pressure gauges to the field chassis.
  5. Field chassis power was disconnected from the SUS-R1 24V power strip and connected to the delta power supply in mechanical room.

Software was updated by P. Thomas and required a trip to EX to reconfigure the networking settings. Jim was able to bring back HEPI but reported oscillations on the pressure gauges.

Headed back to EX to troubleshoot. The Delta power supply was replaced with a Kepco power supply. The LVEA chassis was moved back to the pressure sensors to eliminate the DB9 extension cables. Both changes were done to save time as we were well beyond the maintenance period. Field chassis can be moved back to the half-rack at a later date. Jim reports oscillations are gone.
