Problems described in detail below (this entire procedure takes way too much of our time, effectively still nearly 2 hours!):

Nerea/AE requested yesterday afternoon to shutdown and restart the SASE1 VAC PLC loop once again. We start today morning (wednesday) at 8h30. 
8h30
karabo is not showing status of all devices, see three screenshots (attached). karabo-GUI issue.
These devices have to be shutdown and reinstantiated to show a status and to operate them. 
Several valves and gauges and scroll pumps affected both in XGM of XTD2 and XTD9. 
 
9h00 finally I can close all four vatterfly valves 
 
9h15 Nerea shuts down and restarts the SASE1 VAC PLC loop 
 
9h25 still waiting for karabo to reconnect to Beckhoff PLC (I cannot do anything in karabo, and 
 no current status updates of anything) 
 
9h40 SPB_XTD9_XGM scene has loaded (seems like at least). I start the reactivation procedure (switch 
 on scroll, open valves etc.). Need to reinstantiate several devices. 
 
10h00 SPB_XTD9_XGM: reinstantiate both turbo pumps, CRemotePriority ON, COn, CPump (if CRemotePriority 
 not visible, again reinstantiate) 
      READ ADriveCurrent, ARPMIn several times, both should change from time to time, don't 
 worry about "0" every second read time 
10h05 SA1_XTD2_XGM: reinstantiate both turbo pumps, StartPumpingStation 
      READ ADriveCurrent, ARPMIn several times, both should change from time to time, don't 
 worry about "0" every second read time 
10h10 READ the actual value of the gauges in configurator (not to trust value shown in scene) 
10h15 observe DOOCS RVC300 UHV pressures, open vatterfly valves 
 
10h20 end of intervention
