I put this code in Script console and it can convert value in tag to character  
But the problem is It isn’t show in tag (display)  
What should I do to convert value in tag real-time and show in display.

tagValue = system.tag.read("[default]_Modbus_/UnitId 1/1\_test1-1\_test20/1\_test2")  
character = chr(tagValue.value)  
print character

You’ll want to convert `Mode` to `Alphanumeric` and bind to `Text` rather than `Value`.

You could use an expression binding like this on `Text` to run the script to convert the tag value to an ASCII character:

```auto
runScript("chr(" + {[default]Modbus/UnitId 1/1_test1-1_test20/1_test2} + ")", 500)

```

It may make more sense to do this in a derived tag with this read expression:

```auto
runScript("chr(" + {source} + ")", 500)

```

Then you can bind your display’s `Text` directly to the derived tag.
