Hello,

I have a problem connecting to SIPROTEC 7SJ622 via the front interface. When i try to connect i choose to work with device data and it starts downloading. After a minute of downloading it ends with error saying "Unable to combine settings" and it can not proceed. I tried it on several devices which are:

7SJ6225-5EB90-1HF0/EE L0A, FW 4.64.01, P-Set 4.65.01
7SJ6225-5EB90-1FE0/EE L0A, FW 4.64.01, P-Set 4.65.01

In Digsi 4.9 I use devices with FW version 4.6.

I think I found a solution to this problem. I insert V6.5 in the project then update its parameter set to 4.65 but I don't know if it will work. SIPROTEC devices are on site and I can't access them whenever I want.

Another thing is that when i go to Settings/Setup/Extras/Interfaces it only shows PC-Port setings but there is no System port settings for the Profibus DP communication module. All 7SJ622 devices will be connected to Profibus DP network.

Please, help me solving these problems.

Best regards,
Kris Dimov

Hello Kris,

All settings for Profibus you can find in interface settings.
