Use Data Views to Access Controller Data
About This Chapter The module provides access to controller data for monitoring and
data modification of controller tags.
This chapter shows you how to set up data views of controller tags.
For data views, the module must be in the same chassis as the
controller.
Data Views Overview Data views give you the ability to read from and write to RSLogix
controller tags from a browser interface or an external application.
The module provides web pages that let you configure a set of tags (a
data view) that can be read or written.
A data view consists of an XML file with data tag information The XML
file is in a readable ASCII format. It contains the tag name, data type,
path, display formatting, and privilege access level. Each tag value is
exposed as a separate element and an error attribute is optional.
