Hi!

I have a sample qAds project:

m_qAdsPlcData = new QADSARRAYOFINT(this,851,"10.1.2.15.1.1","10.1.2.15","mydata.data_out",QADSPLCVariable::SYNCHRONIZED,0)

I connect to a slot to update the GUI:

connect(m_qAdsPlcData, SIGNAL(valueChanged()), this, SLOT(update_display()));

Thats works, but i need to use new qt way, to improve the code with lambda expressions:

connect(m_qAdsPlcData, &QADSARRAYOFINT::valueChanged, this, &Display::update_display);

Thats compile, but in execution time i have the error: "QObject::connect: signal not found in QADSARRAYOFINT"

I need help to solve this, i read other cases with the same error, but not in Qads and not try to modify the library before ask here.

Hello,
first: thank you for this great library!
Unfortunately we have a problem with "SYNCHRONIZED" variables. We mostly use it as QADSBOOL. Randomly, these variables are not updated, and we can't get the variables value. Calling value() then is (and stays) always true or false, and any update on TwinCAT side won't call the callback.
This randomly may happen to any of our QADSBOOL variables. Mostly it works as expected, but not always.
