[Dsg-hallb_magnets] [New Logentry] Torus Controller Minor Fault Cleared

[Probir Ghoshal]

Hi Brian
Thanks for helping out.
Please also attach the plots you made and shared earlier.
I am still not convinced with the minor fault sum on torus will trigger the controlled ramp down of solenoid..
But please put the plots in the log book entry for any future reference.
Regards
Probir

While investigating the solenoid controlled ramp, noticed that there was a minor fault on the torus controller.

Below is the fault on the PLC, which as since been cleared.

10/13/2022 8:16:23 AM
(Type 04) Program Fault
(Code 56) Invalid Start and/or Quantity value.
Task:    MainTask
Program:    MPS_Control
Routine:    ProcessResponse
Location:    Line 59

Line 59 is the part where the PLC is processing the slew rate command from the 8-bit DAC on the MPS, which is not being used (the 12-bit DAC is) so the error can be ignored.
