Obsolete Device net Parts

Hi,

I have a failed device net starter modules:
1x 198-DN Series C (Devicenet Control Module)
2x 198-IA2XOW1 Series B (AC Starter Module)

which were installed in 2006, however when looking for spares i am finding out that these are now obsolete!! Whats worrying is that these same starters were installed in 2009 and 2010 at other plants!

Does anyone know what the replacement part for these are?

Its the I/O module part of a device net starter.

You mught want to look at 100-DNY42R

Thanks Jeff. I'll look into these.
