DeviceNet File Input/Output Sizes

I am trying to communicate with a MicroLogix 1500 via DeviceNet. The IRC-5 is the master and the the 1500 is the slave.
 

The 1769-SDN (scanner module on the 1500) gives an error 77 which means that the data table sizes do not match. I am unsure of how to decipher the size of the data tables that the ABB is looking for. I configured the PLC scanner module to 70 input words (the first 66 are read only when using the 1500 platform) and 7 output words. I try to put these values in the ABB controller and the 70 value is not allowed. I tried to just use 4 (70-66) as well but that doesnt clear my error either. I have tried many other combinations in hopes of stumbling across the right one but I dont like to work that way. I wish to understand this more clearly so it is definitive and not a guessing game.

 

Thanks!!

    Check in help in application manual devicenet for DN_GENERIC

    We always go the other way around. The PLC as the master and the robot as the slave. As always unless you get the settings exactly right, it's not going to work.

    For example if you set up your robot slave in RSNetworks to use 64 bytes, then also configure your DN_SLAVE in the EIO file to use 64.
