Data Conversion

(3) Change the allocated bits and words
If necessary, change the allocated bits and words.
Usually, it is not necessary to change the allocated bits and words since their
settings in the conversion source data are reflected in the converted data.
However, if the data is converted from the NT21, NT31, NT31C, NT631, or
NT631C to a conventional model in element units, or if the data is converted
between different direct access types, modification of the allocated bits and
words may become necessary since the range of usable word addresses
differ. For details, refer to Correcting the PC (PLC) addresses on page 466.
(4) Correct the screen data
If the data is converted from a PT model to another PT model that has small-
er screen than the source PT model, it is necessary to modify the screen
data in accordance with the screen size.
If data is converted between a conventional model and a new model, the
data must be corrected in accordance with the conversion destination be-
cause there are many differences between a conventional model and a new
model.
Refer to page 464.
(5) Modify the program.
If the screen data is corrected, the program at the host may have to be modi-
fied. Modify the program by referring to “Correcting the Screen Data Conver-
sion” (page 464).
Correcting the Screen Data Conversion
This section describes how the screen data should be corrected after it has been
converted.
If the screen data cannot be converted correctly, an error message is displayed
on conversion of the data (when changing a PT model or PLC Vendor, or register-
ing a symbol from the symbol manager). If an error message is displayed, it will
be necessary to correct the screen data or the program.
