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.

  • Hi ,
    My understanding of Exclusive Mode, is that it will stop a Standby IO Device sending any requests to the Device, while the primary is active. I do not think this applies to WatchDog or heartbeat messages that the lower levels of the driver implements.
    , could you try the following paramters in the IOServer section:
    [IOServer]
    AlwaysCallStopUnit=1
    AlwaysCallStopChannel=1
    WatchdogPrimary=1 (Only on the Primary I/O Servers is this parameter set)
    Watchdog=0 (Only on the Standby I/O Servers is this parameter set)
