My opc item name include "[ " , so it will show add item failed in pipc log.
how can i do ?
those characters should be OK. What version of PI DA and PI API do you have. Here are some limits on the character length of that field:
PI API PI Server Maximum Length
1.6 or higher 3.4.370.x or higher 1023
1.6 or higher Below 3.4.370.x 32
Below 1.6 NA 32
In the OPC Client, you can export the tag defs to a CSV file: File->Save AS. Please do that and make sure all characters match, including the case. This field must exactly match the item name as defined on the OPC server, including any punctuation, spaces, and case.
