Studio 5000

HMI devices support Logix tag extended property strings, such as tag descriptions. If no languages are set up in the Logix project, the HMI device displays the default extended property strings defined in the Logix project. If languages are set up in the Logix project, the HMI device displays only the extended property strings created for the English-United States language.

Graphic elements that reference unconfigured Logix tag extended properties show an Error icon . These graphic elements handle Logix tag extended properties in specific ways:

HMI devices support the Logix STRING data type. Standard ASCII characters are encoded with values 0 through 127 with each standard ASCII character encoded in a single byte of the STRING data type. The HMI device can read and write standard ASCII characters using this standard encoding.

The HMI device uses UTF-8 encoding to read and write string tags containing multi-byte characters to a controller using the STRING data type. UTF-8 encodes multi-byte character sets by breaking down complex characters, such as Unicode characters, into multi-byte representations. The

controller can then store complex characters in the STRING byte array.
