A User Defined Type (UDT) is a complex type of Tag in Ignition that can be configured to easily control multiple instances. This type can hold multiple other basic types of tags (int, string, etc) as well as other UDTs. Changes made to the parent UDT will automatically be propagated to all children.

User Source

Created Sep 28, 2016 (22:28) , last modified Jun 18, 2021 (16:51) by Unknown User (null)

A User Source in Ignition is a group of users with their associated roles. Ignition uses a role-based security system, ie: each user may be assigned to various roles. Security policies are then defined in terms of these roles, rather than defined for specific users. This allows users to be reassigned, removed, and added without affecting the logic of the security policy. An Ignition Gateway may have many different user sources defined, each governing the security of different aspects of the Gateway. For example, logging into the Gateway configuration web interface might be governed by one user source, while the security for a project is governed by another.

UDP is used by apps to deliver a faster stream of information by eliminating error-checking.
