High Power RF Manpower Usage

Maxwell and Continental

12 months was the estimate given to produce the controls for the PLC systems.

Los Alamos

4 months to make Allen Bradley and scan task modifications required.
2 months to develop a network fault logger like the local one provided
12 months to develop the database
2 months to test and integrate

Notes:

Conversion in PLC not consistent - required debugging and EPICS DB changes.
PLC use of registers as scratch pad during scan cycle required PLC debugging.
Complex logic for HPRF ladder logic increased debugging time.
Control channels not implemented in PLC required debugging time
Each change to the PLC took at least a week as there was no support for integration
Limits and gains in PLC significantly added to EPICS DB size as each of these values had to be brought into EPICS as separate records - not fields of one record.
