PLC for Ham Radio beacon control

I AM NOT A STUDENT LOOKING FOR SOMEONE ELSE TO DO MY ASSIGNMENT FOR ME.

I have the software, cables, etc... and several Allen Bradley SLC's. I'd like to program one of them to run a beacon. I dabble in PLC programming as part of my job, not really a programmer. 

I'd like to come up with or copy a way to write values into an algorithm to use a PLC to send a CW message on a beacon station. Starting with some simple stuff, callsign, location, etc... And the perhaps working up to local weather conditions as I have several analog input cards. 

I could "brute force" write the rungs for callsign and location but I would rather have some way to use MOV statements or similar to write the required values into counters or whatever to control the CW output.

Any constructive thoughts on this are highly appreciated. I've searched for others doing this but have found very little on this subject and lots of posts about PLC - Power Line Communications.

Thanks,
