5. OPERATION
5.3 Compilation
During compilation, an edited source program is translated into a ROM format file (object file)
executable by the PMC. Uncompiled programs cannot be transferred to the ROM writers (PMC
writer or FA writer) or RAM for the PMC. With PMC-R series, PMC-QC, PMC-NB. compilation can
be performed in one of two modes:
normal mode and condensed mode.

Transferred to the ROM writers
l Condensed mode
With PMC-R series, PMC-CC, PMC-NB, a source program can be compiled in condensed
mode. When a ladder with the same number of steps is compiled in condensed mode, the
size of the created ROM format file is smaller than that created in normal mode. As a result,
condensed mode has the advantages listed below.
@ A larger C language area can be allocated.

0 Time required for compilation is reduced.
0 Time required for transfer from the personal computer to the PMC is reduced.
@ A ROM module with a smaller capacity may be used.
