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.

  • Strange thing is that server2 is communicating fine and then just stops polling after 16:49:55
    After a silence of 10 seconds the RTU terminates the TCP channel (FIN, ACK at 16:50:05)

    Is it something you did at 16:49:55, or did this happen without a reason? Does the I/O server syslog of server2 show any errors at that time?
