Hi Mr. Clapperton, for the SFK4H requirements please refer to the release notes in the downloaded app file. You should have ctrlX 1.12.6. In order to see I/O states displayed, you may need to refresh your browser by pushing the reload button or by switching tabs back and forth. The ClearError function appears to be available (however, I am currently working with the upcoming release). In case it isn't, here is a workaround: You can use the DataLayer app under ctrlX Settings for finding the path to the function you would like to call. Please consider that the backwards compatibility at present has some limitations and unfortunately some settings have to be restored manually. Best regards, Sergio
