If the block transfers already exist, you can get to the module config screen even though you get the warning "no module exist in i/o configuration" warning. This often occurs when the program was originally written prior to RSLogix or was uploaded and saved as a new file without confi data.
Double click on I/O config, then double click on the first entry under adapter. (it should show your processor model number correctly) Edit the entries to match your system and hit okay. Be sure to choose the correct addressing type and chassis type.
Next, doulble click on the chassis under Chassis Type in the I/O config.
That will open up a list of the slots in that chassis. Next, add the IFE module to the correct slot by double clicking on the field in the Module Type column where it belongs. This opens up a dialog that lets you choose the module from a list.
Once the module type is listed in the I/O config, double click it and you will get this screen:
Just hit the Done button. (DON'T HIT AUTO PICK!)
You'll get this error message, but don't worry, here comes the strange but cool part:
Click OK to acknowledge the error, and you'll get another one.
Hit Okay again. Now double click on the module again, and presto, you get a message that makes sense asking you if data already exists. Answer yes, since there is already block transfer logic written with dta tables assigned.
Now, magically, you're in the module config screen without having to manually search for and enter the correct address details. RSLogix5 will find them for you, once you're familiar with the odd way in which this happens. Save the file so, next time, it'll take you straight there without having to go through all these hoops.
