RTU560 No respons to commands IEC101
I receive DPI/SPI from the RTU to my Scada system over my Tetra radio IEC101.
But the RTU does not respond to any commands iI send to it. Not GI either.
I have a Serila Analyzer and i cant se anything wrong.
From SCADA:CA:68 Cause:act. P/N=Pos. Double cmd. IOA: 22003 Execute ON Short
From RTU:CA:68 Cause:spont. P/N=Pos. Double-point. IOA: 5005 IV:0 NT:0 SB:0 BL:0 INDET Time 164:27.359 IV

PFA some screen shots I had taken using VINCI IEC101 analyser. In the screen shots I have captured the transmission of an SCO from SCADA and the response from the RTU-520 to the SCO command.
I do not know why RTU560 is not responding to commands.However, you may be able to find some clue from the attached screen shots.
