I'm trying to configure an S7-1512R system.  I thought I'd got everything fixed but I cannot get rid of some hardware compilation warnings and cannot find enough info in the manuals to work out why and whether it's a serious problem or not.

The warnings are "[network item] in [MRP domain] does not support an H-Sync forwarding rule."  These are output for an IO device and a switch in the MRP ring even though those devices support MRP.  From what I understand this forwarding is about reducing network traffic beyond the ring so it won't make a blind bit of difference for the IO_Main device since all it's ports are ring ports anyway.  But is the SCALANCE_Sw going to be sending all the H-Sync frames out to the non-ring ports, and what extra functionality/different type does that switch need to prevent this?

IO_Main is an IM 155-6 PN ST, 6ES7 155-6AU01-0BN0

SCALANCE_Sw is an X206-1, 6ES7 155-6AU01-0BN0

Thanks in anticipation
