We are using Concept on our BOP computer for the operation of pumps and monitoring of levels. Low key stuff. The original contractor left us with a functional PLC but no tag names in the ladder logic. Does anyone have a way to add the names to the points in the logic? The contractor will come back on site, at a price, but if there is a way to do it in house we would appreciate it. We just upgraded the WONDERWARE software to 10.0 on the machine. Thanks.

 

From the description that you have provided it appears that the system integrator utilized direct addressing instead of the variable name when creating the project.

Once you have the project open in Concept, you can use the Variable Declarations option under the Project menu (F8 is the shortcut key). This will open the variable editor.

You can then add the variable name to the correct direct address. In your logic if the direct address was used during the development it will not automatically be replaced by the variable name that you created. The variable name and address information will be displayed in the lower left hand status bar if you highlight the direct address with your mouse.

 

By "points in the logic" I assume you mean within the PLC. IF that is the case, then unfortunately there is no other way than opening up Concept and manually adding it.

My next question (IF that is not feasible) is what is your end goal?

Within Wonderware InTouch, are the tagnames created with descriptive words, or PLC register addresses? (e.g. 40103 vs Pump001_Speed). If they used descriptive words, then you could create an InTouch window (or popups), to assist maintenance for example, by using simple text fields on the window. Again, "IF" they did this, you would simply dump the entire tagname dictionary into a CSV format, open it up in Excel and sort the I/O type tags and delete the rest. In the CSV for I/O you will see columns that represent the tagname and the ITEM name (which is the PLC register). Then, use this filtered out excel file as your template to create a window that maps the addresses to the tagname.

ex: Maintenance Window

StationName_Pump001_Speed - 40130
StationName_Pump001_RunHours - 43765

I am guessing, since I saw you are in "Utilities", that your maintenance guys want to be able to quickly identify what address belongs to the value they see on the screen, so IF something goes wrong, they know where to go in the PLC.

I believe you can do this in house (if by some miracle all my assumptions are correct).

I work for Wonderware in the Southeast, but I would suggest that you look for the local WW distributor and take the InTouch class. This will absolutely help you, and ultimately might be cheaper than bringing in an Integrator or Vendor.

I can only take you so far however, but be confident that at least development within InTouch is VERY easy to do.

Good Luck & Happy Holidays.

 

There should be a tagname dictionary that will show you the direct address and the data type. This screen also has a place for a variable name.
