Note
Some devices only support a subset of the data type listed. Please check and ensure the data type selected matches the data type of the tag you intended to link to on the device.
-
- Default
-
The default initial value. The tag will be initialized with this value when the project starts.
- Expression
-
Enter expression to perform data scaling, value conversion, and any engineering unit conversion.
- Read Level
-
This column determines the tag's security level for reading. If the user login with user level lower than the value here, server will ignore the user's request to return the data. The highest security level is 1000 and it is set to 0 by default. It must not left blank.
- Write Level
-
This column determines the tag's security level for writing. If the user login with user level lower than the value here, server will ignore the user's request to set the data. The highest security level is 1000, it is set to 0 by default. It must not left blank.
- Log
-
Database name defined in Database Task. Server will log the tag value to this database based on log frequency or mechamism specified. This is the only thing need to do at back-end configuration if trending for a tag is required.
- Log value
-
An additional attribute that defines the log frequency or mechanism for the tag.
-
On Change - log the tag when its value changes.
-
On Timer - log the tag when the timer specified triggers.
-
On Change + On Timer - log the tag when either its value changes or when the timer specified triggers.
-
- Retentive
-
Database name defined in Database Task. Server will save the tag value to this database upon changes. This retentive feature comes handy when a tag needs to start up with previously set, used or received data. System will store the last good value so that this last good value will be used upon next system start up, or upon communication error. Retentive value will always overwrite Default value when presents.
- Read Role
-
Displays a list of role defined for selection. Check or tick the roles to grant read access to users with the role selected. If no role is selected, all users are allowed to read this tag.
- Write only tag
-
An additional attribute that defines whether the tag is write only tag. Set to true to mark this tag as write only. No user is allowed to read this tag even though he is given read Role.
- Write Role
-
Displays a list of role defined for selection. Check or tick the roles to grant write access to users with the role selected. If no role is selected, all users are allowed to write to this tag.

Tip
Use copy and paste method for the tag name to avoid mistakes (capitalization, dot location) in typing the longer tag names.
