Help with Micrologix 1500

When I attempt to go Online with a Micrologix 1500, I get a "DiagnosticStatus Failed 0x10" message. I've attempted to connect via DF1 and ethernet but both paths give me the same error message.

Note: I beleive this problem started after attempted to modify the ML1500's CH 0 baud rate settings.

Any help with this problem would be great.
Thanks!

If it's only the baud rate that has changed, then you should be able to "Auto configure" the DF1 driver from RSLinx.

Thanks paraffin power

That's (auto configure in linx) what we had to do to get back online.

thanks again
