Device Configuration Workflow in the new Control System - Best Practices

Issues to consider when configuring / integrating / removing accelerator devices for / in / from the FAIR control system. Some of the procedures are not automated and require the involvement of experts. Therefore some operations may take some time.

How to integrate NEW devices ( )

• nomenclature for new device is required (-> M.Kühn)
• hardware integration / connection to frontend computer (SCU, microIOC, ...) (-> device/hardware experts)
• driver configuration with expert application if required (e.g. for stepper motors) (-> device/hardware experts)
• FESA configuration
  • instantiation file for frontend computer
  • FESA database entry (DEV|INT|PRO)
• devices in the production environment (PRO) should be usable by applications -> an LSA database entry is required (LSA developers must be informed about new devices in FESA database) (-> FESA developer, LSA database maintainer)

How to rename existing devices ()

• new nomenclature is required (-> M.Kühn)
• driver configuration with expert application if required (e.g. for stepper motors) (-> device/hardware experts)
• FESA configuration
  • instantiation file for frontend computer (-> FESA developer)
  • FESA database entry change (DEV|INT|PRO) (-> FESA developer)
• devices in the integration/production environment (INT/PRO) should be usable by applications -> an LSA database entry change is required (LSA developers must be informed about new devices in FESA database) (-> FESA developer, LSA database maintainer)

How to remove existing devices ()

• driver configuration adaption with expert application if required (e.g. for stepper motors) (-> device/hardware experts)
• FESA configuration
• • removal of device-instance from instantiation file for frontend computer (-> FESA developer)
  • FESA database entry change (DEV|INT|PRO) (-> FESA developer)
• INT/PRO environment: an LSA database entry change is required (LSA developers must be informed about removed devices in FESA database) (-> FESA developer, LSA database maintainer)
• devices can be removed from nomenclature list (->M.Kühn)
