Ignition 8.3 Siemens Enhanced Driver OPC Item Path Syntax

I don't think we document the item path for symbolic addressing at all. That being said, quotes are required for individual parts of the path that contain special characters.

For example, these addresses all point to different tags:

  • "Block.One"."Tag.One"
  • "Block.One.Tag".One
  • "Block.One".Tag.One

Then, I think these addresses are also valid but point to one of the above tags:

  • "Block.One.Tag"."One"
  • "Block.One".Tag."One"
  • "Block.One"."Tag"."One"

Most, if not all, tag names that have non-alphanumeric characters will have quotes around them when browsing. Some characters may be fine without quotes :person_shrugging:
