Allow nesting of UDTs if fields are more than allowed threshold

Optimize the generation of user-defined tags

Since R2023a

Model Configuration Pane: PLC Code Generation

Description

The Allow nesting of UDTs if fields are more than allowed threshold parameter allows Simulink^® PLC Coder™ to nest user-defined tags (UDTs) when the number of UDT elements exceeds the value set in the Maximum number of fields allowed in a UDT parameter, which has a default value of 500. Rockwell Automation^® does not allow the import of structured text code when the number of UDT elements exceeds 500.

Dependencies

To use this parameter, set the Target IDE parameter to Rockwell Studio 5000: Routine or Rockwell RSLogix 5000: Routine.

Settings

off (default) | on

On: Enable the nesting of UDTs in the generated code when the number of UDT elements exceeds the value set in the Maximum number of fields allowed in a UDT parameter.
Off: Disable the nesting of UDTs in the generated code.
