Attribute Description

2009-04-01T12:08:00.000Z.

The local tags component defines local tags in the Add-On Instruction. The L5K
format for defining a local tag is the same format for defining a tag in a program or
at controller scope. For more details on defining a tag, see Chapter 6 Defining a
Tag Component on page 105. For L5X format, you specify the default data for the
local tag with a <DefaultData> element. Define the <DefaultData> element the
same as a <Data> element. See Chapter 1 Data Formats on page 39 for more
information on the <Data> element format.
