Mixed state scenario
A mixed state scenario occurs when a component contains child components with different online and offline only states or allocation states.
This scenario shows how FactoryTalk Design Studio displays online indications in the System Explorer tree. This helps you observe which components are inside the controller you are monitoring. In this scenario, a green rail appears next to the parent FactoryTalk Smart Object CIP100. A standalone Smart Object TK100_Wash_Tank and the inherited program zControl from the library definition behind CIP100. The green rail indicates the child components are online and in the controller being monitored.
Item number | Description |
|---|---|
1 | Green rail indicates child components online and in the controller being monitored |
2 | Parent FactoryTalk Smart Object |
3 | Inherited Smart Object instance |
4 | Inherited Smart Object instance |
5 | CT100_Conductivity is not in the controller that is currently online |
The mixed state icon indicates at least one of the child elements is in a different state. You can expand the elements to observe the child elements and the different states. There are two inherited Smart Object instances CT100_Conductivity and LT100_Level. The green rail does not appear next to CT100_Conductivity. This indicates it is not in the controller that is currently online. This difference in green-rail state causes the mixed-state icon to show on the parent component and on the ancestors of the parent component.
IMPORTANT:
Online and offline indicators appear based on how elements are named. No icon appears and the green rail is present when a component with this name exists offline and has been deployed to the controller. There may be differences between the online and offline components, such as different tags or ladder logic.
