Ken, Sorry, I missed your point before. Does this mean that TIM blocks are processed in an extended BPC while other blocks in the same overloaded CP may be processed in an overrun? My understanding was that in a control station, all blocks were processed without exception, the BPC overrunning to allow that. Seems a bit odd if the TIM blocks are treated differently, as that could change the normal compound/block processing order. Which manual was that quote from?
