Parameterized Tag Paths

Parameterized Tag Paths

The tag path for MES Counters and Tag Collector Paths in the OEE Downtime Tab can be parameterized with "{Equipment Path}" to utilize indirection and provide for a more rapid development of the production model. 

Both back slashes and forward slashes or a combination of both can be used. 

Example

Before: [default]\Enterprise\Site\Area\Line\InfeedCount

After: {Equipment Path}\InfeedCount

If your tag path is not built with the same hierarchy as the Production Model, you can still parameterize the path using parts of the Production Model path.

Before: [default]\Enterprise\Site\Area\Line\InfeedCount

After: [default]\Enterprise\Site\{Equipment Path:3}\{Equipment Path:4}\InfeedCount

Also: [default]\Enterprise\Site\{Equipment Path:3,4}\InfeedCount

Here the number indicating the Area in the production model hierarchy from the enterprise level is 3, so Equipment Path: 3. Similarly Equipment Path: 4 for the Line. Supported Configurations {Equipment Path}- replace with the full equipment path for the item {Equipment Path:N}- replace with Nth item in the equipment path {Equipment Path:M,N} - replace with Mth item to the Nth item in the equipment path Example: {Equipment Path:1} = Enterprise {Equipment Path:2} = Site {Equipment Path:3} = Area {Equipment Path:4} = Line {Equipment Path:5} = Cell or Cell Group or Location {Equipment Path:6} = Cell if part of a Cell Group

To check how your parameter expression evaluates, use this function:

from com.sepasoft.production.common.model.core import Path
eqPath = 'Enterprise\Site\Area\Line\Cell'
tagPath = '{Equipment Path}/tagname'
 
Path.replaceTagPathParameters(tagPath, eqPath)
