energyApp EPICS application¶
energy is an EPICS application including:
A database file and corresponding autosave request file that contain the PVs required by the energy.py base class.
OPI screens for medm
An example IOC application that can be used to run the above databases. The databases are loaded in the IOC with the example substitutions file, energy.substitutions.
Base class files¶
The following tables list all of the records in the energy.template file. These records are used by the energy base class and so are required.
energy.template¶
This is the database file that contains only the PVs required by the energy.py base class energy.template.

$(P)$(R)EnergyMode |
mbbo |
Contains the energy mode, options are Pink, Mono and White |
$(P)$(R)Filters |
stringout |
Contains the list of filters (material and thickness) added manually |
Energy change¶
Record name |
Record type |
Description |
|---|---|---|
$(P)$(R)EnergyChoice |
mbbo |
Contains the pre-calibrated energy values in keV in the format mode value, i.e. Mono 20.00 |
$(P)$(R)EnergyInRange |
bo |
True when the energy selected is within pre-calibrated min-max energies |
$(P)$(R)EnergyCalibrationUse |
mbbo |
set to select use of Pre-set or interpolation |
$(P)$(R)EnergySet |
busy |
when set to 1 starts the energy move |
$(P)$(R)EnergyTesting |
bo |
when set beamline component move is disabled |
$(P)$(R)EnergyBusy |
busy |
when set to 1 the beamline is busy with the energy move |
Shutter control¶
Record name |
Record type |
Description |
|---|---|---|
$(P)$(R)CloseShutterPVName |
stringout |
Contains the name of the PV to close the shutter |
$(P)$(R)CloseShutterValue |
stringout |
Contains the value to write to close the shutter |
$(P)$(R)OpenShutterPVName |
stringout |
Contains the name of the PV to open the shutter |
$(P)$(R)OpenShutterValue |
stringout |
Contains the value to write to open the shutter |
Shutter status¶
Record name |
Record type |
Description |
|---|---|---|
$(P)$(R)ShutterStatusPVName |
stringout |
Contains the name of the PV with the shutter status |
Energy Move PV Names¶
Record name |
Record type |
Description |
|---|---|---|
$(P)$(R)EnergyMove0PVName |
stringout |
Contains the name of the PV that will move in an energy change, both to a pre-selected and to an interpolated position |
$(P)$(R)EnergyMove0PVDesc |
stringout |
It is used to store the PV description. If available this will be derived from the EnergyMove0PVName description if not it will be created using the EnergyMove0PVName itself. These PVs will be used as key entry in the dictionary storing the pre-calibrated position for each motor. |
Energy Pos PV Names¶
Record name |
Record type |
Description |
|---|---|---|
$(P)$(R)EnergyPos0PVName |
stringout |
Contains the name of the PV that will move in an energy change to a pre-selected position. This motors will not move to an interpolated position. |
$(P)$(R)EnergyPos0PVDesc |
stringout |
It is used to store the PV description. If available this will be derived from the EnergyMove0PVName description if not it will be created using the EnergyMove0PVName itself. These PVs will be used as key entry in the dictionary storing the pre-calibrated position for each motor. |
medm files¶
The following is the MEDM screen energy.adl during a scan.
The status information is updating.
The following is the MEDM screen energyEPICS_PVs.adl.
If these PVs are changed tomoscan must be restarted.
