We are not sure how this initially happened, but somehow some constants for water control were changed in the <R> core. This caused a misoperation of the unit when we tried to quickly ramp down its MW output (controller kept applying full water at all times and not regulating as it should for emission control, we had to trip the unit offline to remain compliant).
We identified the changed constants, and attempted to perform a reboot so that it pulls the configuration from the EEPROM, and this did not work. We had to manually change the values in <R>. The EEPROM appears to have the correct information, so the problem is that this information is not successfully getting to <R>. Any ideas where we can look to help identify our problem?
PS: I may have spoken out of terms on some items. I am not an I&E guy, I am in transmission planning and am helping our generation folks try to get to the bottom of this. I was not onsite during troubleshooting, so I am speaking from second-hand information that was relayed to me from the plant.
