Other functions
This section describes other functions of the KV-D20.
User message function
This function corresponds to the user message function of the Access Window of
the KV unit. The Access Window displays numeric values only, but the KV-D20
displays comments as well.
Messages are displayed with 32 characters (16 characters x 2 lines).
The Access Window displays the desired number stored in DM1950 when a certain
relay turns on. However, the KV-D20 displays the contact comment for the device
specified with the value stored in DM1950, in the same manner as the operator
screen.
Note that although the KV unit is running, the Access Window does not display the
correct value while the user message is displayed.
To cancel the user message, press the
key. (Pressing the key is effective
even while the key-lock function is set.)
■ Type of device to be displayed
Note: Do not enter a value in DM1950 other than those above.
Example
When the value specifying a certain relay is stored in DM1950 and the relay turns
on, the comment for the relay is displayed on the KV-D20 screen.
The following ladder program displays the message "Add screws" when relay 0001
turns on.
Note 1: 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. Please note when "~" is used in the middle of a
contact comment, it is displayed as "➞".
Note 2: 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.
