Fundamentals of COM 265
Errors detected during compilation of the IP 265 user program
COM 265 provides adequate support for compiling IP 265 user programs. An IP 265 user program
reserves memory space on the IP 265 ( Section 9.4.1). When a compiler run is started, COM 265
checks to see whether the IP 265 user program is compilable and whether there is sufficient space
in the IP 265's memory.
If the IP 265 user programm cannot be compiled, COM 265 aborts the compilation and displays an
error message. You can screen details on the cause of error and recommendations on how to rectify
it by pressing <F7> "Info".
Example: Error message displays in the COM 265 "Compile" form and recommendations on how
to rectify the errors.
Compile
The IP265 program is too long!
The program could not be compiled! Try recompilation after:
a) Removing superfluous IP265 parameters and CSF language elements, or
use other language resources for a more compact solution
b) Assigning bit parameters to the same byte address
c) Assigning debounced 24V inputs to one of the two address groups
(I0.x with x=0,1,3,7 and I0.y with y=2,4,5,6) or leave out debouncing
d) Dividing the program between two IP265s and using I2.x, Q2.y

Figure 8-6. Example: Error Message Display in the "Compile"
If the IP 265 user program is free of errors and not too big, the following message is displayed upon
successful compilation:
"The program was compiled successfully and utilizes xx % of the IP 265 load capacity."
The value xx % indicates the amount of IP 265 storage taken up by the IP 265 program when it is
loaded.
