InTouch tag names can be a maximum of 128 characters. Each Supertag ParentInstance\ChildMember\Sub-member can be a maximum of 128 characters. The maximum length of a tag name places a restriction on references to Supertags.
A Supertag reference can be a maximum of two templates (ParentInstance\ChildMember) and one member deep, as shown in the following figure.

Note: A Supertag sub-member can be up to 62 alpha numeric characters if the attribute type is not set to any existing Supertag. A sub-member based on a Supertag type can be only up to 32 alpha numeric characters long.
Each member in a Supertag template is accessible in the standard format currently used to access the dotfields of standard InTouch tag types. The Supertag reference syntax is supported throughout InTouch where standard tags can be used. For example, a valid Supertag dotfield reference is:
TankFarm\Tank1\Pump1RPM.RawValue
Remote tag references also support Supertags. For example, a valid Supertag remote reference is:
PLC1:"TankFarm\Tank1\Pump1RPM.RawValue"
