I upgraded from a PLC 551 to a 552, to go from 16K to 32K memory. Everything works fine except that RSlogix tells me I have reached the memory limit at 16K which gives me a compiling error.
Memory used: 12226 instruction words + 2373 data tables
Memory left: 62 instruction words left.
(which is not coherent with the processor type above: 1747-L552..)
I tried to redownload.. no difference.

thanks for the help!
 
The part number and version are the same as two previously upgraded machines which worked properly, and the I/O config shows the new processor. Everything is identical to the previously upgaded lines EXCEPT the memory on the latest upgrade still shows only 62 words left, the same as before the new processor was intalled.
