The tag standard is based on prefix and suffix. The prefixes are used to connect tags to the objects and suffixes define function. The suffixes are defined by the symbol libraries used. A symbol library for building automation is included and its suffix list is described in chapter "Symbol library and naming convention".
In the tag name AHU01_GT11_PV, the AHU01_GT11 is the prefix and _PV suffix. In the symbol library for building automation, _PV represents the measured value for the sensor GT11 of the system VS01.The tag VS01_GT11_CSP represents the calculated set-point for the same sensor. Avoid using suffixes containing underscore (_), since the last underscore in the tag name is in much of the functionality in Web Port interpreted as the delimiter between the prefix and suffix.
