Gridcon PCS integration - Issue

I am trying to add a Gridcon PCS settings, once I do this I got the following error

java.lang.IllegalArgumentException: The following BooleanWriteChannels have no Write-Value: gridcon2/CommandControlWordModeSelection,gridcon2/CommandControlWordTriggerSia,gridcon2/CommandControlWordFundamentalFrequencyModeBit1,gridcon2/CommandControlWordFundamentalFrequencyModeBit2,gridcon2/CommandControlWordBalancingModeBit1,gridcon2/CommandControlWordBalancingModeBit2,gridcon2/CommandControlWordHarmonicCompensationModeBit1,gridcon2/CommandControlWordHarmonicCompensationModeBit2

Is the config available on the github repository, for the example?

I asked my colleague wgerbl to reply to this post, because he has the most experience with the MR GRIDCON PCS.
