Tag Name Database

C-more tags are used as an essential part of most operations. A Tag Name represents how the project uses the tag.

To keep Tag Names organized and easy to locate, C-more provides a Tag Name Database you can access from the Database menu.

This topic shows you how to add, edit, 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 edit the parameters.

Configure the Tag Name Database

1. Click 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 to associate with this tag.

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

• Set up devices in Add a PLC Device to a Project.

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

• Consider naming tags so they are easy to find and replace portions later using Find and Replace.

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

5. Enter the ASCII String character length.

Note:

Characters only applies to the ASCII String Data Type. The maximum length is 128 characters. Choose the shortest length possible to optimize communications and performance.

6. Select Retentive if you want the tag to retain its value when the C-more panel loses and restores power.

Note:

Retentive only applies to Internal tags.

7. Select the Memory Type.

8. Enter the memory address location.

Tag Name Database Operations

• Fill Down: select a tag to create consecutive tag names with PLC addresses.

  The tag copies, appending a number to the tag name: "(1)" for the first copy, "(2)" for the second, and so on. Each new tag is assigned the next consecutive PLC address.

  Note:

  Fill Down does not check if the next address is already assigned to another tag.

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

  Example:

  Change tag names that include "WEST" to include "EAST". The tool changes tag names everywhere they appear in the project.

  Note:

  Replace renames the current tag. This is different from Find & Replace.

• Import: import an existing Tag Name Database from an .xls, .csv, or .l5K file. See Import a Tag Name Database for more details.

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

• Filter: click Filter to narrow results by Partial Text, Read/Write Attributes, Device Name, or Data Type.
