Few questions, While upgrading to Freelance 2016 version have you upgraded firmware of Controller AC 900F and CI 930F via Configure tool before downloading program ? Second,The CI 930F is blinking red or continuous red color led ?
To recover, Seems it's inhouse testing then just take out battery from controller, power off controller > 5 min, power on again load the firmware of version you want for AC 900F and CI 930F. and then make whole station download to controller.
Perform scan bus at profibus master object and check for slave number appears for S700 ? it should work...
Also recommended to read through RN and getting started manual from version 2016.Hope that helps...
