Greetings to all,
no, I haven’t gotten lost ... just doing some money making work for the boss man ... incidentally, I don’t even have an internet or email connection at home ... it’s my way of keeping family life and my work life separate ...
anyway ... I’ve had a little bit of time to do some more exploring through the posted program ...

even though Gsquare hasn’t really answered all of my questions, it looks like the highlighted modules are the ones he’s having trouble with ... when I right-click the IFE and select “display module”, I can get right to the module configuration screen ... even though there are no block transfers for this module present in the ladders ...
on the other hand, when I right-click on either of the OFE’s and select “display module”, I can NOT get to the module configuration screens ... and again, there are no block transfers for either of these modules present in the ladders ...
these conditions make me think that the entry of the IFE was somehow aborted part way through the module insertion process ... if I’m correct in this, I suggest the following plan of attack ...
first right-click on the IFE module and then DELETE the IFE module from the Chassis Display table ... if you’re prompted to “Delete I/O points” do that too ... once the module has been completely deleted, then shutdown the RSLogix5 software ... completely ... then start it back up ...
now go back and reinsert the IFE module again ... when you reach the “Enter Module Addresses” screen and are prompted for the addresses associated with the block transfers, go ahead and click the “Auto Pick” button ... BUT ... before you click the “Done” button, CHANGE the block transfer control block addresses to something completely new ... I’d suggest using a brand new BT24 file ... yes, I know that the BT23 file (named “NEWBLOCKXF”) is already available and unused ... but I’d still go ahead and make a new one ... of course this step will have to be done with the processor in the Program mode ...
now display the module configuration screen and go through the regular setup procedures ... then while still on the module configuration screen, have the software automatically add the block transfer rungs ...
finally, with the processor still in Program mode, (cross your fingers) “Accept” the new rungs ... maybe that will fix your problem ...
IF (and that’s a big IF!) this procedure works, go back and try the same approach on the OFE modules ... be sure to reinsert them one at a time ... and I’d recommend that you shut down RSLogix5 completely after deleting each module and start up fresh before you reinsert each module ... this might be overkill but what-the-heck ... and make CERTAIN that the addresses that you manually type in for the OFE block transfers are unique ... specifically, do not overlap the addresses used for the IFE ... or for the first OFE while inserting the second OFE ...
finally ... I’ve seen situations like this happen in the classes I teach ... once in awhile while installing an IFE module, a student will somehow get the system “hung-up” and be unable to continue ... it only happens on very rare occasions so I’ve never been able to identify exactly what sequence of operations causes the problem ... all I know is, when we go through all of the steps I’ve listed above, we can successfully get the thing to work ... I do know that this “insert-the-new-module-and-automatically-write-the-rungs” procedure is taken care of by an “applet” in the RSLogix5 software system ... my best guess is that when the programmer gets something in the normal sequence of events out of step, then the “applet” gets hung in a loop or something along those lines ... shutting down and restarting the RSLogix5 software seems to “make it better” ...
anyway ... I’d try this out ... if it doesn’t work, let us know what happened ... I’ll be setting up the lab this weekend for a class next week ... if all else fails, I’ll be glad to try to set up an extra chassis with an ASB adapter and try to duplicate your problem ... let me know if you need me to do this ... I should be able to have the results by Monday or Tuesday ... BUT PLEASE – tell me exactly how you have the DIP switches on the chassis backplane and on the ASB adapter set up ... we’d certainly like to be able to compare apples to apples here ...
and incidentally, I’ll try that Online “manual write” to the BT files at lunch ...
