Good morning,
I am new in the ignition world and I am having some troubles with system.queryTagHistory function. When I use it to retrieve a tag which has a special character in the path, the query return null value.
I guess it is a problem with tag encoding conflict between ignition and my db server, which is by the way a sql server, but so far I haven’t manage to solve it.
the tag path I use is: plc_tv_1/Dati_Produzione/Velocità macchina m_min
while the string retrieved is: plc_tv_1/Dati_Produzione/Velocità macchina m_min
Thanks in advance for your help!
