CTT test case execution for Data Access Percent Dead band |OPC Certification and Interoperability Testing|Forum|OPC Foundation

Hi,

I have executed the Data Access Percent Dead band CTT test cases. There is one test case Err-003 is skipped and reason for that is No analog values with Eu Range property available. The nodes which configured in settings all are Analog data with EU range. and If I configured non analog data without EU range property then already passed test cases are failing. So my question is

1.Is it required to pass all  the test cases from optional units?

2.Can I run and execute two times with two different configured settings(Non Analog for Err-003 test case and Analog for remaining test case)  to pass the unit cases?

Thank you

Prasad.
