Parameter Text Length defines the initial Text Length for data read from the field device for Tags and BLOCK:PARAMETERS created using this parameter. Text Length indicates the length of data read. For Text Tags and BLOCK:PARAMETERS this determines how long the text string is. This is very driver dependent. Usually text length is the number of ASCII characters. For example, a 40 indicates a forty-character length tag for most drivers. See the specific Device Driver Guide for more information.
