  • DL205 Remote Serial IO Problem

    I have a controller that lost its programming. We went through and reloaded the controller but the Serial IO network did not come back online. This Serial IO stuff is a bit out of my knowledge bank so I am hoping for a little help here.

    From reading I am assuming that the DL205 had some custom IO mappings and when we reloaded the ladder it did not reload the custom mapping settings. Unfortunately, we do not have any documentation on what the mappings would have been set to. Does anyone know if there is a way to recover the mappings by looking through the ladder? I see that you are supposed to fill out worksheets to calculate the original setup, but I am wondering if we can reverse engineer based on the final code?

    Thanks for any help!

    Please post part numbers for the CPU and for the communication cards on both ends.
