Muon Kicker: Display Status of Kicker PSU

[kjwoodsISIS]

As a muon scientist, I need to see the current status of the Kicker PSU, so that I can monitor its behaviour.

Acceptance Criteria

1. I can view whether the Kicker PSU is currently switched ON or OFF
2. I can view the voltage readback of the Kicker PSU (measured in kV).
3. I can view the current readback of the Kicker PSU (measured in mA).

Notes

1. required by Muon Front End: Monitor Kicker #3071
2. The Kicker PSU is controlled by a National Instruments DAQ device (DAQ-Mx).
   1. See Kicker_Separator_Schematics.
3. The ON/OFF status of the Kicker PSU is read from a PLC.
   1. The PLC is a Schneider Electric M580 device
4. The Kicker PSU voltage & current can only be read from the DAQ-Mx. At the present time, they cannot be set (hardware limitation).
5. Note: IBEX does not communicate directly with the Kicker PSU. It communicates with the NI DAQ-Mx. In order to read or set the voltage and/or current on the PSU, there needs to be some sort of calibration or lookup between the NI DAQ-Mx and the PSU.
   • The calibration (scaling) relationship is:
     • Kicker Voltage: 0-10V (DAQ) = 0-45kV (PSU)
     • Kicker Current: 0-10V (DAQ) = 0-15mA (PSU)

Glad there was success, let’s assume it’s the need for up to date DAQ until proven otherwise.

Luckily the muon front end can have a recent DAQmx install, which is where we need to use the 4 slot chassis on a live system

Tom, could you add that comment to the appropriate ticket?

Hi,

Ok, after updating to daqmx 18.0 it has worked. The problem I got was as per https://forums.ni.com/t5/Multifunction-DAQ/cDAQ-9184-201401-Error/td-p/3608487 in their case they restarted the unit and unplugged a module while running, this then prompted a “installing device driver box” and it then worked. In my case after a upgrade to 18.0 and restart I still had a light grey funny looking cDAQ-9185 as before, however this time when I right clicked “add device” it went into find new hardware and installed a driver, and now I see all the cards OK. SO I don’t know if it was my version of max/daqmx got in a funny state, or whether you need daqmx 18.0, but I can see all the cards now at least

• I have created an OPI for the kicker (Muon Kicker: Monitor Oscilloscope Trace #3406 needs reviewing first) (https://github.com/ISISComputingGroup/ibex_gui/tree/Ticket3071_Add_IOC_KICKER branch)
• The IOC created ( Ticket3071_Add_IOC_KICKER branch on IOC, IOCTestFramework and EPICS-Kicker, Ticket3071_Add_IOC_KICKER_submodule on EPICS branch) works as required (tested with the DAQ). Just needs checking that it works from within the client with the OPI.
• There is some boilerplate code to connect to the Schneider Electric M580 PLC using Modbus to read the ON/OFF status of the Kicker PLC. I have not tested this code and we don't know how we will talk to the device. This feature probably doesn't work currently.
