SCADA has got three types of tags, I/O tag (external), virtual tag (internal) and runtime (memory) tag that add during runtime. Only I/O tag is associated to I/O count and virtual & runtime tags has no limit and is completely free!
The tags are systematically organized under device folder tree, and there’s no limit to create the associated device so long the I/O count is within the license configuration. For instance, if you purchase a license for 32 I/O count, you can then configure 32 tags at different addresses for one device, or 32 devices at different IP with only 1 tag.
setTag() functions throughout your entire project, from front-end within browser to backend at server side.
