Why is this worth talking about? Many systems are burdened with numerous "stub" taglists, archives and everything under the sun. People try to make sense of them, but there is nothing systematic. The techniques available using DBDOC will let you unburden your system of deadwood, leaving useful information that is cross-checked. Some sites give up on the process, but this prevents them from having a good cross-check on the HMI because they create logic and thus tags in the EWS.
INFI 90 HMI systems can be separated into these classes:
- Master taglists in the HMI - 800xA, SPlus, PGP, PPB, Conductor NT and PCView
- EWS contains the HMI taglists - Conductor VMS and WinSODG
As sites have moved to more modern HMI systems, reconciling the taglists in the EWS to match the master taglists in the HMI systems becomes important. Here is how to do this using DBDOC.
- Identify the actual taglists used by the consoles. You should be building them in DBDOC already.
- Identify the taglists in Composer or WinTools that need reconciliation.
- Build as many subprojects as needed to have simple parallel lists of tags.
DBDOC has numerous resources for supporting taglist work if you need more:
- Extracted SQLite database containing all the tags built into the project
- Individual DBF files for the taglists from both EWS and HMI systems
- Combined taglists of Composer and WinCAD tags
There can be significant benefits to keeping the HMI and EWS taglists synchronized. We would be happy to help you understand the data DBDOC makes available to you and how to take advantage of it.
