Series 6 to 90/30 Comm via Bus Controllers

I have 2 non- redundant PLC Series Six CPU's. I need to communicate to a 90/30. My idea is to locate a 90/30 locally to the Series Six and communicate via Ethernet. The hard Part is reading the Series Six CPU's via bus controllers to the 90/30 bus Controllers. I know datagrams are involved but have not had to do the actual programming.

Take a look at using Global Data instead of datagrams. There is an example program in chapter 7 of the Series Six bus controller manual, GFK-0171. Once you have
