How to update the model name of a registered HART product:
Character Limit for Product Names:
The Long Tag is limited to 32 ISO Latin 1 characters for HART products.
The ModelName is limited to 32 ISO Latin 1 characters for FOUNDATION Fieldbus products.
It is recommended to use 18 characters or less for best visibility on displays.
Character Encoding Set:
ISO Latin-1 /IEC 8859-1 characters are acceptable. The codes within 128-159 are not allowed (i.e. Windows-1252 uses this range however this is reserved by ISO for legacy control characters).
The following characters may be excluded and removed from the registered device model name to maximize interoperability:
Copyright ©, trade mark ™, registered ®, and Em dashes – —.
Upon publishing the device in our Product Registry, the “More Information” field allows for these additional characters if you need to display them.
