Hi Team,
I was going through the test cases of Attribute Service where, I found one test case which says “client physically able to specify NaN as value of variable or property”. Whose expected result is:
Expected Result: Client is expected to send a valid MaxAge. Note: Client may override the MaxAge with a default value. Likewise, it may simply reject the user-input and not issue the Read.
My understanding of this test case: This test case is somewhere related to a variable/property containing NaN as a value & client is trying to read that variable/property. While having this type of value we need to check how OPC client behaves ?
Is my understanding correct or am I misunderstood something. What does Physically means here ?
Please help me in understanding this test case.

Hi Dipika,
the test case asks to define a MaxAge with a “NaN” value to see how the Client behaves in this case. As the expected results are saying, the client is expected to not send a “NaN” in its request but either send a default value or declining the operation.
The word “physically” is kind of misleading and could be removed from the text. It stands for “the client allows to set a NaN value” somehow.
