Before create a drive rs232 in rslinx appears the message: device recognized.
And now i cant comunication.
Its possible donwload files to card flask like firmware and others to fix the comunication problem?

Sorry english

Hi Pablo,

Can you give me some more information about the steps you took?

Based on what you’re describing, the only issue I would see occuring is a disconnect during the firmware upgrade which is rare, but does happen. In older PLCs that’s a major fault and it probably won’t be possible to recover the PLC.

Are you able to connect to the device over BootP? Do you see anything in RSLinx when you scan? The RS232 driver should work regardless of the IP address, so I’m not sure why it’s not showing.

Which firmware did you upgrade the PLC to? Did you get a successful firmware flash confirmation?

Thanks,
Vlad
