I have a problem with Qt, I use QOpcUa with open 6254 to read and write tags on a PLC but sometimes the following error occurs: "error / client Inactivity for Subscription" and my program crash.
I have identified the problem and this happens because the PLC is writing in this tag at the same time.
I would like to know if there is a way to check the availability of the tag before writing?
I have already learned about the subject and there are functions like StatusCode or monitoringStatus but I can't use them properly.
void NodeLoad::writeOrderNumber(QString value)
{
//if("method that checks the availability of the tag" == true)
OrderNumber->writeAttribute(QOpcUa::NodeAttribute::Value,value,QOpcUa::Types::String);
//else qDebug() << "Error";
}
If the tag is not available at the time of writing, the following error occurs:

I make web app for restaurants. when client in restaurant on web page selects dishes, he clicks "order", and waiter will receive a push notificarion on his phone via fcm for web. Will waiter receive all notifications through fcm for web? I need them to be delivered in 2 minutes maximum, can firebase fulfill my requirements? Thank you
Realistically, most messages will be delivered in under a few seconds, assuming the target device is active and has a good network connection. In practice, there is no way to ensure the timing of the delivery of a message, as the network could be poor or missing, and the device could be in a battery-saving state the delays receipt. If you want to increase the chances of the message getting to the device, use a high priority notification, as described in the documentation.
Hi am a little confuse on how this works base on firebase quotas on the free plan, been testing my app for months now and never came across this issue. How can i resolve or detect this issue where after couple of hours my quota is exceeded.
