The following steps explain how to build the tag list

Build the tag list
In [System Parameter Settings] add [BACnet/MSTP Server] driver
Click [Tag Manager]
Click [Tag Manager]
Configure tag information
3.1 HMI Device ID: Set the range to 0 ~ 4194302.
3.2 Tag Name: Add these tags: Analog Input, Analog Output, Analog Value, Binary
Input, Binary Output, Binary Value…
3.3 Specify the quantity of the selected tag, the allowable range: 1 ~ 100
3.4 [Add Tag]: According to the selected tag and the specified quantity, the added
tags will be shown in the list.
3.5 [Delete Tag]: Delete a single tag or multiple tags.
3.6 [Import Tag] [Export Tag]: Import an existing CSV file or export current data as a
CSV file. Please note that current data will be removed after importing a CSV file
