Tag Name Database

C-more tags are a necessary part of most operations. A Tag Name shows how the project uses the tag.

To keep Tag Names organized and easy to find, C-more gives you a Tag Name Database that you can open from the Database menu.

This topic shows you how to add, change, and delete tags in the Tag Name Database.

System Tags are a separate list of predefined internal tags. Use these to configure objects and functions. You cannot change the parameters.

Configure the Tag Name Database

1. Select the Database tab.

2. Select Tag Name Database.

Add a Tag

1. Click the Add button.

• The Tag Name - Add window opens.

2. Select the device for this tag.

• If the tag is not for a configured device, select Internal.

• To set up devices, refer to Add a PLC Device to a Project.

3. Enter a tag name that identifies the tag purpose.

• Use tag names that are easy to find, so you can change parts of them later with Find and Replace.

Example: Use Find and Replace to change Pump 1 Motor Start to Pump 2 Motor Start.

4. Select the data type that matches the PLC address: Discrete, Unsigned Int 16, or Signed Int 16. This selection sets the memory types available in the Memory Type drop-down list.

5. Enter the ASCII String character length.

Note:

Characters applies only to the ASCII String data type. The maximum length is 128 characters. Select the shortest possible length for the best communications and performance.

6. Select Retentive if you want the tag to keep its value through a power cycle. Retentive tags will be overwritten on project download.

Note:

Retentive only applies to Internal tags.

7. Select the Memory Type.

8. Enter the memory address.

Tag Name Database Operations

• Fill Down: select a tag to make a sequence of tag names with PLC addresses.

  The software copies the tag and adds a number to the tag name: (1) for the first copy, (2) for the second, and so on. The software gives each new tag the next PLC address in sequence.

  Note:

  Fill Down does not examine the next address. Another tag can already have that address.

• Replace: change a tag name everywhere in the project.

  Example: Change tag names that include WEST to include EAST. The tool changes tag names in all locations in the project.

  Note:

  Replace changes the name of the current tag. This is different from Find and Replace.

  Highlight: This makes it easier to quickly identify tag issues

  • Unused Tags - Highlight any tag that is not assigned to an object or used in a configuration (email, mqtt...).

  • System Tags - System tags are internal C-more tags.

  • Duplicate Tags - if two or more tags point to the same device and device address, they can be highlighted. Duplicate tags are allowed, but can make troubleshooting difficult. If the Find/Replace functionality creates new tags, they will have the new name, but use the same PLC address. Duplicate tags will highlight those and simplify fixing the target address.

• Import: import an existing Tag Name Database from an .xls, .csv, L5X, L5K, or XML file. Refer to Import a Tag Name Database for more details.

• Export: make a CSV or XLS file of the existing tags in the project. Refer to Export a Tag Name Database for more details.

• Filter: click Filter to apply a filter: Partial Text, Read/Write Attributes, Device Name, or Data Type.
