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 Olivier,

    I think Stuart's comment is valid, or at least it was before the introduction of Exclusive Mode. Not setting [IOServer]Watchdog=0 leads to concurrent communication of 2 masters to the same RTU. We experienced the same issue with IEC61850 RTU units from a certain company.

    Like Stuart, I'm also curious if turning on Exclusive Mode prevents this periodic watchdog communication from happening when the parameter is not set to 0.
