I have setup Fronius Weld Equipment Option on R-30iA, it should be similar. The software automatically maps the required I/O at controlled start based on how many arms are connected to the controller. I would not recommend manually mapping I/O unless you are familiar with the signals that are required by the Fronius.
Not sure what you mean by "can't get anything else to work"... provide more information. To switch the operation mode (Job Mode -> Synergic), you need to change that under the process select in the weld schedule.
If you are referring to the Fronius and not being able to change setting then you need to turn it to internal on the Fronius.
defaults - system
interface set up
Welding perimeters ( external )
changes external to internal then you can edit on the weld set but remember to change it back
