Subscription error Bad-TooManymonitoredItems

[fendou-jk]

Hi kevin，

When using the following method to monitor changes in point values, I only added 7 points. But it reported an error message of TooManymonitoriedItems. Is my subscription listening method incorrect? How can I implement a subscription to avoid this problem?

What server are you connected to?

as a client you don’t have much control over this, it’s up to the server how many MonitoredItems per Subscription, per Session, or overall per Server is too many. 7 seems low - are you sure that’s all you’re creating? Are there other subscriptions or sessions?

Thank you for your reply. I will contact the server personnel to confirm the monitoring items information. Also, I would like to confirm if there are any issues with this subscription method in the code?
