Hello !

First some information about my system:
• OPC-UA Server
• Prosysopc version 2.1.0-435

Some setting information’s on the client site:
• Publishing-Interval =100
• Sampling-Interval = 0.0
• QueueSize = 1000000
• maxNotifiactionPerPublisch = 0
• notifiactionBufferSize= 1000000

I have two items (sendControl and receivedState) in my opc-ua server that I am using for the handshake.
The first one (sendControl) is a monitored item. So when his value has changed I receive in message from OPC-UA server. If I receive a message from opc-ua server, I first use the method client.readValues in order to read value of further parameters in the opcua-server then I run some tasks on the client site and at the end I change the value of the second one (receivedState) while using the method client.WriteValues from Prosysopc API. My problem is that sometimes the write or read process takes ca 300 ms
Any suggestion?

Thanks!
Owen
