Dear all, I have an Allen Bradley Control panel with SLC L542C 5/04 CPU, it is used to control an RO water desalination unit, unfortunately the CPU has a fetal Fault and need to be replaced, the only available one is 1747-L542A 5/04 CPU, the problem is when downloading the PLC Program to the new CPU, using RSLogix 500, it failed due to smaller memory of A series CPU 24K while the C series CPU was 32K, is there any way to reduce the program size to be used with 1747-L542A 5/04 CPU? what is a proper way to get the new CPU run with the control program? Thank you all in advance.

thank you very much, I really appreciate your help.

Thank you very much Joe. Would you please help to convert these files, it may have symbols and comments, what version of RSLogix 500 do you used here, I have RSLogix Micro Starter Lite, is it enough?   4351890A.RSS 4351890A_28_10_06.RSS
