Tags
A "tag" is a data variable that LETS retrieves from the control. For example, if LETS asks for the tag named "PARTS_COUNT", the control would return the current parts count; when a machine is stopped, the ERROR_CODE tag returns a code that indicates why the machine is down.

The SmartPAC 1 and 2 have 15 standard tags that are sent to LETS.  Tag counts for machines other than presses can vary depending on the amount of data that needs to be collected from the machine. In order to calculate OEE, LETS needs a minimum of two tags: Parts Count and Production Rate/Speed.

The following hardware recommendations apply to a typical LETS Standard Version installation.
