Peg Condition

When the DRL changes a local TTG's Current Loss Percent value, it shall:

• Save the time of the event in the TTG's RT-DB record called "Loss Start Time"
• Save the new Current Loss Percent value in the TTG's RT-DB record
• If the TTG's old Current Loss Percent value is not equal to 0, then:
  • Calculate the duration of the time that the TTG's Current Loss Percent was set to the previous value based upon "Loss Start Time" and the current time
  • Determine which TtgTmLossRateRange-X measurement to update based upon the previous TTG Current Loss Percent value and the system-wide LossRateMax1, LossRateMax2, and LossRateMax3 values
  • Update the selected TtgTmLossRateRange-X measurement with the calculated duration of time
