Create aliases

The steps in your step program use aliases to reference object attributes. Aliases are used to

• write outputs once a step is active (On Entry Write)

• trigger the step or jump condition

• write outputs after the step or jump condition is fulfilled (On Exit Write)

• specify the output value to be written when an Alias appears in the output matrix as a pass by reference value.

You must define an alias before using it to read from or write to an attribute.

Note:
- You cannot map an Alias to an attribute from the Step Program tab. Do this on the Aliases tab. For more information, see Assign an attribute reference to an alias.
- You can create up to 1000 Aliases in a single Sequencer object.

To create an alias from the Step Program panel

1. Select the Step Program tab. The Step Program panel appears.

2. Select on the Add button near the Outputs entry. An additional column is added in the Outputs area with a default name as column header.

   

3. Enter a name for the new Alias.

   Note: You cannot add an Alias if the Alias Configuration (PrgAliasConfig) is locked, even if the Step Program (PrgStepProgram) is unlocked.
