Roger that. I was picking up on the "with no shift between them" from your 
earlier message and conflating that with the (confusing) Beckhoff Infosys docs 
which show S1 starting from same time reference as S0 (i.e. same phase). I see 
my interpretation of the ET1100 docs agrees with yours, which is a relief :)
