There are only 5 types of data support in IEC 60870-5-101, Double Point (DP), Single Point (SP), Measure Value (ME), Double Command (DC) and Single Command (SC) whereby Measure Value is 16 bit integer, Single Point, Double Command and Single Command are Boolean data type and Double Point is unsigned 8 bit integer. To configure a tag entry for Double Point, Single Point or Measure Value will need to set the Input Tag of Tag Properties to "True", hence they are both read-only tag and the value can't be changed by using setTag() function call in Script.
