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.
...
Tag Creation
To add a new tag, click Add tag icon, and Edit Tag pop-up window will appear.

Item | Description | ||
Tag Name | Input the desired tag name | ||
Path | Outlines the group path of the tag | ||
Type | Allows the user to select from 12 possible data types. The available fields in the advanced options tab will change based on the selected data type.
| ||
I/O Device | For remote tags, select the external device to associate the tag with. The user can check the name of external devices by clicking Tools > I/O Device Editor. For shared tags, a Data Server must be set up to allow communication with these tags. | ||
I/O Address | Enter the external device address to associate the tag with. The user must enter the address using the device’s addressing method. For example, for a CIMON PLC, valid bit addresses include “X00”, “Y1E”, etc. This field is enabled only when an I/O device is selected. | ||
Persistent | When this option is true, the last state of the tag is stored when the project is closed. When the user executes the project again, the tag values will be reloaded. | ||
Value Changed | With this option enabled, a user-defined script or action list will be performed when the tag value changes. | ||
Quality Changed | With this option enabled, a user-defined script or action list will be performed when the quality of the tag changes. In this case, quality refers to the communications status of the tag. |

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. | ||

LINT(INT64) | Signed 64-bit integer. Enables the Clamp Mode, Deadband Type, and Scale Mode advanced options. | -9223372036854775808 – 9223372036854775807 | |
USINT(UINT8) | Unsigned (non-negative) 8-bit integer. Enables the Encoding, Clamp Mode, Deadband Type, and Scale Mode advanced options. | 0 – 255 | |
UINT(UINT16) | Unsigned (non-negative) 16-bit integer. Enables the Encoding, Clamp Mode, Deadband Type, and Scale Mode advanced options. | 0 – 65535 | |
UDINT(UINT32) | Unsigned (non-negative) 32-bit integer. Enables the Encoding, Clamp Mode, Deadband Type, and Scale Mode advanced options. | 0 – 4294967295 | |
ULINT(UINT64) | Unsigned (non-negative) 64-bit integer. Enables the Clamp Mode, Deadband Type, and Scale Mode advanced options. | 0 – 18446744073709551615 | |
REAL(FLOAT) | 32-bit floating-point number. Enables the Clamp Mode, Deadband Type, and Scale Mode advanced options. | -3.403e+038 – 3.403e+038 | |
LREAL(DOUBLE) | 64-bit floating-point number. Enables the Clamp Mode, Deadband Type, and Scale Mode advanced options. | -1.798e+308 – 1.798e+308 | |
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. | ||
