Greetings… I am having an issue writing a value to an memory tag via script. The error generated is: GatewayException: Error serializing parameters. caused by NotSerializableException: org.python.core.ReflectedArgs Ignition v7.9.3 (b2017060210) Java: Oracle Corporation 1.8.0_131 The memory ta…

Yeah, so the one-shot button actually has a method on it named setValue which is what you’re getting when you try to reference the property. Try this instead: OSValue = event.source.getSetValue() Just an unfortunate naming clash here.

Everything is getXxYy() and setXxYy() “under the hood” but are also given the Python-friendly property accessors that you’re accustomed to using. Like I said, this is an unfortunate naming clash where the property called ‘Set Value’ or ‘setValue’ clashes with a method name on the button.

Thank you. Good info. I could find no info in the manual regarding this syntax. Your results may vary.
