PItoPI 1> Tag SINUSOID rejected.Source tag already
configured for tag SINUSOID.
Cause UniInt tag loading behavior. When UniInt is disconnected from /host Historian
Server on startup it will does not resume tag loading where it left off. Instead it reloads
the tag list from the beginning. Any tag that was loaded before the disconnection will be
rejected after reconnection with the stated error message. This error message can
safely be ignored. The tag is loaded and will receive data.
Resolution See PLI 19689OSI8. This issue will be addressed in a future UniInt/PItoPI release.
