CPU memory 
Use the CPU memory calculation worksheet, Table B-11, to 
determine if a CPU requires additional memory. Each line in the 
worksheet is a system variable and is referenced by a line 
identification (ID) letter. The line IDs also appear in the formula 
column. The result of solving a formula is then placed in the 
“Results” column. 
Enter the values for each variable in the “#” column on the same 
line. 
Replace the variables in the formula by the value entered in the 
“#” column having the same letter as the formula. 
Calculate the formula and put the results in the “Results” 
column. 
Determine the memory size required as indicated at the bottom 
of the worksheet. 
Note: The Systems Definition Utility will prevent you from 
downloading if the compiled project database exceeds the 
amount of memory on the CPU.
