Notes on contact comment display
When entering a contact comment, note the following:
•
Enter a contact comment using alphanumeric characters.
•
To enter a space to the left of a contact comment, input "~" (swung dash) at the
left end of the comment with the LADDER BUILDER for KV. Spaces without "~"
at the left end will be ignored. When "~" is used in the middle of a contact
comment, it is displayed as "
➞
".
•
Contact comments can be displayed only when the LADDER BUILDER for KV
Ver. 1.5 or later is used and the compression transfer of contact comments is
not selected.
•
Even the contact comments for ladder programs created with LADDER
BUILDER for KV Ver. 1.0x or KV-LADDER can be displayed on the KV-D20
after being transferred to the KV unit with the LADDER BUILDER for KV Ver.
1.5 or later.
•
"Not transfer" is initially set as the contact comment transfer setting of the
LADDER BUILDER for KV Ver. 1.5 or later. To display contact comments on
the KV-D20, enable the contact comment transfer setting with the LADDER
BUILDER for KV Ver. 1.5 or later.
