Ticket_8284_Allow_certain_values_to_be_editable_without_restarting_IOC

[isaachilly]

Description of work

Added a MACRO for the McLennan IOC that allows a user to be able to set the ASG group of the MOTOR record. The ASG group controls what ASLs (either 1 or 0) are allowed to do I.E (1, read) allows pvs with ASL 1 to be read etc. This concept was used here to allow user to set the JVEL, HLM and LLM without having to change them in the IOC macro screen and thus have to restart the IOC. If they set the MOTOR_ASG to DEFAULT and then start/restart the IOC it means the access control is set to read & write.

• Mclennan: Allow certain values to be made available to edit without restarting the IOC IBEX#8284

To test

• Check the code's quality
• Check tests are written correctly and pass
• Set (or don't set) MOTOR_ASG manually in your globals.txt and check functionality by spinning up McLennan IOC using C:\Instrument\Apps\EPICS\support\IocTestFramework\master>run_all_tests.bat -t mclennan -a. Remember to let tests run through before ctrl-c otherwise you have to find the procserve process in task manager details and end that before you can start up the IOC again

Acceptance criteria

• A security group is created that allows for the JVEL, HLM, and LLM to be set or not based on a specific macro which defaults to not allowing changes
• There are tests both with and without that macro set to ensure the beaviour is as expected

Code Review

• A copy of the manual has been placed on the shared drive
• Pertitent information has been stored in the wiki
• Does the IOC conform to IBEX standards?
  • PV naming.
  • Disable records
  • Record simulation
  • Finishing touches
• If an OPI has been modified, does it conform to the style guidelines?
• Do the IOC and support module conform to the new build guidelines
• Have the changes been recorded appropriately in a PR for release notes?
• Is the device's flow control setting correct? For most devices flow control should be OFF.

Functional Tests

• IOC responds correctly in:
  • Devsim mode
  • Recsim mode
  • Real device, if available
• Supplementary IOCs (..._0n where n>1) run correctly
• Log files do not report undefined macros (serach for macLib: macro to find instances of macLib: macro [macro name] is undefined...

Final steps

• Update the IOC submodule in the main EPICS repo. See Git workflow page for details.
• Reviewer has merged the associated PR for the release notes
