If an object in a PPCL statement fails, the statement continues to use the object's last known value. For example:

MIN(RMMIN,RM1TMP,RM2TMP,RM3TMP)

If RM1TMP is a physical object that fails when it has the lowest value of the three RMTMP objects, the MIN statement will set RMMIN to the last known value for RM1TMP.
