Configure Logic Paths

Connections that start at nodes that have a logical result output can be configured to create separate logic paths in a policy model. Specifically, you can specify whether or not a successor node will be executed based on the logical result of the preceding node. The GE Digital APM system will execute only the branches of a policy model where the logical result of a node matches the logic path defined for the corresponding connection.

Note: If you do not configure a logic path for a connection, a Yes path is assumed but does not appear on the model.

Before You Begin

• Be sure that you understand the basic principles for working with a policy model.
• Add and connect nodes in the policy model.

Steps

1. Access the policy within which you want to configure logic paths.

2. In the Design workspace, select the connection for which you want to specify a logic path.

   The Properties window for the connection appears.

   

3. In the Logic Path box, specify whether the connection should be followed if the logical result of the preceding condition is true or false. Specifically:

   • Select Yes to specify that the connection should be followed when the logical result of the preceding node is true.
   • Select No to specify that the connection should be followed when the logical result of the preceding node is false.

4. In the Policy section of the toolbar, select .

   The policy is saved.

Example: Separate Logic Paths

Consider the following policy model.

In this example, you can see that:

• The Condition node evaluates the DA Reading Value that is associated with the OPC Tag record to determine if it is greater than or equal to 900.

• The Condition node is connected to the following successor nodes:

  • Email Analyst (through the Yes connection)
  • Create Recommendation (through the No connection)

Based on the connection properties, the following logic will be applied when the policy is executed:

• If the DA Reading Value is greater than or equal to 900, an email message will be sent. This logic is determined by the Yes logic path specified for the connection to the Email Analyst node.
• If the DA Reading Value is not greater than or equal to 900, a Policy Recommendation record will be created. This logic is determined by the No logic path specified for the connection to the Create Recommendation node.
