Its main use is probably simply as an interface between IO pins (such as the PID gain pins) and output pins. You can't normally net Output to IO pins. However, there have been occasions where I have been inconvenienced by the fact that output pins get written to each and every cycle. I just can't recall the circumstances, possibly a comp which wanted to the use the same variable internally. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
