HPRF - notes

I do not have the time estimates…

The multiple master control of outputs significantly complicated the database design and the driver

Signals were displayed on the Panel Mate in one set of units, were in different units at the variables we were given - again - complication in the database and requirement for save/restore.

Signals in the Panel Mate were used as scratch pad registers between Panel Mate update cycles and EPICS would see these intermediate values.

Complex logic for HPRF control and interlocks were in the PLC - producing a 3 inch listing that was time consuming to take over

Control channels from EPICS did not work initially - they were not implemented in the PLC

Each change to the PLC took at least a week - no support for integration
