Too many 'elseif' statements in OptoControl may cause an error during download


Applies To:

FactoryFloor Software - OptoControl

Versions Affected:

Problem was discovered in version: R4.1c


Symptoms:

If an OptoControl strategy has an OptoScript block with numerous elseif statements and the strategy is downloaded to a controller, error –52 Stack full is returned.


Workaround:

Removing some of the elseif statements from the OptoScript block allows the strategy to download successfully.


Resolution:

The number of elseif statements supported by a controller will vary by model and other memory related factors. When using many elseif statements in an OptoScript block, users should adjust this number based on what is supported by their controller model.
