Appendix C​. Tag optimization

The optimization of tags is an essential part of tag configuration. It can make the difference between good performance when collecting tag values and an interface that gets bogged down with a plethora of requests to a number of PLCs with varying degrees of performance. For input tags, tag configuration optimization is relatively easy and only requires a logical grouping of related tags. For output tags, tag configuration optimization is critical and can make a difference on whether or not the tags ever even get updated.
