Dear Colleagues, I have a communication problem with a new AK1703 RTU and existing Sicam PAS (Version 5.11) via IEC 101 . I have tried both balanced and unbalanced modes with 9600 and 2400 baudrate and suitable PAS config. I have set RTU to try both modes; *M-CPU PRE:0 as balanced point to point mode with 9600 baudrate *M-CPU PRE:1 as unbalanced mode and link address with 2400 baudrate (an older existing Sicam e-RTU is communicating via this baudrate) I can see the values come from PRE:0 and PRE:1 ports with IEC test software. (Does that mean, there is no problem on AK1703 side?) When I connect AK1703 RTU and Sicam PAS physically (2-3-5à4-5-6) , the connection seems to be running as current state on PAS screen as “green” color. But in the value viewer screen, Although the Rx,Tx can be seen “valid”, the signals (analog and digital) seem “invalid” situation. Could you explain where is the problem? Where we should check?
