Interlocks use item names to indicate an interlock condition on the main Equipment. You define the item name for the target equipment using the Equipment Runtime Parameters Grid.
To manually define an equipment runtime parameter:
- In the System Model activity, select Equipment.
- On the menu below the Command Bar, select Runtime Parameters.
The list of equipment runtime parameters will display in the Grid Editor.
- Add a row to the Grid Editor.
- In the Cluster field enter the name of the cluster
- In the Equipment field enter the name of your target equipment e.g. Pump1, Valve1
- In the Name field enter "Interlock_StateItem". This indicates that an alternative item name (entered in the Value column) has been defined.
- In the Value field enter the value of the item name e.g. Open
If the Name and/or Value fields are left blank then the default item name value "Running" will be used to indicate an interlock condition. However, precedence may change if the global INI parameter [Interlock]StateItem has been set. Refer to [Interlock]StateItem for more information.
- Set the IsTag field to FALSE.
Note:If this field is set to TRUE, interlocks will not function correctly.
- Click Save
