Data Change Reports
Description
This counter indicates the number of Data Change callbacks received by the FactoryTalk Linx Gateway OPC UA server. It is a server-level cumulative count and reflects the requests from various OPC UA clients.
If this counter’s value changes from its default value of 0, the data is being sent to the client. However, if the counter remains at 0, there is a loss of communication between the client and FactoryTalk Linx Gateway, and the issue may lie outside FactoryTalk Linx Gateway. Refer to the product documentation for FactoryTalk View SE and FactoryTalk Linx for troubleshooting assistance.
