Differences between Earlier Models
This section explains the differences in screen creation and programming between the NT30/NT30C and the
NT31/NT31C as well as the NT620S/NT620C/NT625C and NT631/NT631C. The -V2 versions of the
NT31/NT31C and NT631/NT631C are described here. For details of the differences between different versions of
the NT31/NT31C and NT631/NT631C, refer to
Differences between PT models without the -V1 suffix and PT mo
-
dels with -V1 (page 434) or Differences between -V1 and -V2 PTs (page 436).
Refer to
1-2 Functions of the NT31/NT31C and NT631/NT631C for details on functional differences between the
PT models (page 4).
Reference:
The NT30/620 compatible mode can be used to reduce the differences with the
NT30, NT30C, NT620S, NT620C, and NT625C and allow their screen data and
user programs to be reused easily. Refer to
Appendix C for details (page 441).
