I am converting a SLC 500 to a DL06. I have figured everything out except one bit. In my SLC program their is a bit B3/15, this bit has no output. I am hoping that someone might know what this bit is intended for.

It may have ben set/reset by an HMI-display connection.

I do not have a HMI, and this bit is relevant to the machine operation. I noticed both NC and NO of this bit are in a rung with a counter in them.

A normally open and normally closed contact in series creates a "Never True " condition. A normally open and normally closed contact in parallel creates an "Always True " condition. No coil instruction required.

In which case you can replace the NO and NC b3/15 bit with either sp1 (always true) or sp2 (never true).
