Could you do a "show interface brief" and "show interface" on the HP switch and paste it here?
I would remove the trunks as I can't see why this is needed in your setup..
Verify that Route based on the originating virtual port ID is selected on vSwitch1 and on the two configured portgroups (PLC and Proces).
Remove the trunks on the HP switch and tag/untag required VLANs onto the individual ports which were used previously as a part of these trunks..
Quick config needed for the HP..
conf t
no trunk 23,47 Trk10 Trunk
no trunk 24,48 Trk10 Trunk
vlan 1
untagged 23,24,47,48
vlan 40
tagged 23,24,47,48
vlan 41
tagged 23,24,47,48
WARNING: You might have some network hickups when doing this..
What switch model do you use.. ?
