I have downloaded a program into a new compactlogix 1769-L23E B1B and I cannot connect to it with ethernet. I get the yellow question mark and it has the red x on it. I did have to download new firmware to the plc before I could download the program. The plc came with revision 1 on it and I loaded the version 19.13 onto it. I also installed the EDS file for that major revision into my RSlinx. The program that I downloaded to it is already used on other machines so I think the program part of it should be good. Any suggestions would be greatley appreciatted. Thank you.
