I have Freezing problem at Telvent HU-AF.

murat

I am using telvent RTU and Power Scada a Project. But between RTU with Power Scada is disconnecting communication at different time (for example 3 day or 1 week or 3 week). Communication protocol is modbus tcp/ip. RTU have two port; port1 for server 1, port2 for server2.

  • Can you clarify what happens exactly? Does Citect RunTime freeze and then the communication stops, or is it the other way around: Communication stops and then Citect freezes?

    Also, do you run Citect in single process mode (Client, I/O Server, Alarm Server, Report Server and Trend Server as a single Citect32.exe instance)? Or do you run your project in multi-process mode?

    If something (for example a SQL-query or file operation) blocks Citect in single process mode, then the communication will stop as well and the client animation will freeze also.
    Multi-process mode is recommended if your project configuration allows it. It might require some engineering though.
