Priority in I/O comment

SYSMAC CPT saves ladder program in SSS program (*.SP1) and use this file
to import I/O comment.
S I/O comment of CVM1/CV series can not be imported with Support Tool.
S With SYSMAC CPT, it is not possible to save ladder program of PLC with "-Z" in
a file with an extension .SP1. Therefore, Support Tool can not import I/O com-
ment of ladder program for "-Z" created with SYSMAC CPT.
When the I/O comment table at Support Tool has an existing I/O comment or
when both word I/O comment and its bit I/O comment exist in ladder program to
be imported (e.g., 0005CH:DDD, 000512:EEE), priority will be as follows
(smaller number takes higher priority):
(1) Existing I/O comment in Support Tool (in I/O comment table)
(2) I/O comment of bit in ladder program to be imported
(3) I/O comment of word in ladder program to be imported
