When creating a tag, use a name that follows the criteria listed below:

  • The following special characters are not allowed: $, #, +, /, ?, ., {, }, [, ].

  • Tags are not case-sensitive (i.e. dig and DIG will give a duplicate name error).

  • The user cannot use the same tag name more than once in the same tag group. However, tags may use the same name if they are in different tag groups.

Tag Group Creation

If the user has too many tags in a single pane, finding and managing individual tags may be challenging. Tag groups allow the user to organize tags based on category, with a tree structure for subordinate tags. The grouped tags are displayed and managed in the Tag Editor pane.

To add a group, click Add tag group icon in the Tag Editor window to create a tag group. After pressing the icon, a text field will open in the Tag Editor window where a name for the tag group can be assigned.

Data Type

Description

BOOL

Represent ON/OFF status, 0 or 1, True or False, or other values with only two possible states. If a boolean tag is tied to a device address with more than one bit, then any value other than one will be treated as a one.

Do not have Advanced Settings section on the Edit Tag pop-up window.

Analog

Represent 8, 16, 32, or 64-bit numeric values. Choosing the correct data type for interpreting your data (INT16, UINT32, Float, etc.) is crucial.

Analog refers to multi-bit numeric values within Canvas but not necessarily values with an analog input source.

STRING

Stores a string value composed of ASCII characters. For local tags, strings up to 22 characters long can be created. For remote tags, strings will use a contiguous data block on the target device.

  • It is important to verify that the data type of every tag matches the data type used within the paired device. If there is a mismatch, data may be incorrectly represented or manipulated.

  • For data types that span multiple addresses (namely 32-bit double words), only the first address is needed. The address of the remaining words or bytes is implied. Note that Modbus devices typically only send and receive one 16-bit word per address. Therefore, Modbus double words may not be directly accessible via a single real tag.
