There are three modes for comparing ladder programs. The comparison
result changes depending on each mode.
Table 3.13.1(a)
Mode
Explanation
A
It is a mode suitable for confirming the content of the changes in
the ladder.
Compares the addresses respectively with the symbol.
Compare symbol types in the case of extended function.
(e.g.) When the data of No1 and 2 in table 3.13.1(b) are compared,
no difference is detected. When the data of No3, 4, and 5 are
compared, difference is detected.
B
It is a mode suitable for comparing a ladder without symbols (e.g.
ladder in CNC) with the ladder with symbols (e.g. .LAD file).
Do not compare the symbol. (Compare only the addresses)
(e.g.) When the data of No1, 2, 3 and 4 in table 3.13.1(b) are
compared, no difference is detected. When the data of No5 is
compared, difference is detected.
C
It is a mode suitable for comparing ladders of the symbolic
programming (edited by using the symbol). Do not compare the
addresses if symbol exists. Compare both addresses when
symbols are undefined for both programs.
(e.g.) When the data of No1, 2, and 5 in table 3.13.1(b) are
compared, no difference is detected. When the data of No3 and 4
are compared, difference is detected.
