1-2-3 Additional Functions of the V2 Versions
The V2 versions of NT31/NT31C and NT631/NT631C are supplemented and
enhanced by the following functions.
The V2 versions are compatible with the high-speed 1:N NT Link as well as the
earlier standard 1:N NT Link.
Operands (values referenced by equations) can be registered to allow the PT to
perform calculations automatically and write the results of those calculations to
numeral memory tables or words in the host.
The new device monitor function can be used to change the PC’s operating
mode or display/change values in the PC’s memory areas. The PVs of several
words can be listed with the device monitor.
PT operations and inputs can be disabled from the PC if interlock bits have been
allocated in the PC for the corresponding PT touch switches, numeric inputs, or
string inputs.
The following displays can be performed with lamp or touch switch guide charac-
ters:
•
Display several lines of guide characters.
•
Switch the display between different guide characters when OFF and ON.
•
Display the numeral memory table contents as guide characters.
•
Display the string memory table contents as guide characters.
The word configuration of the PT status control area and PT status notify area
can be set to emulate those of the NT30/NT30C or NT620S/NT620C/NT625C;
this mode is called NT30/620 compatible mode.
When the PT is operating in NT30/620 compatible mode, it will be equivalent to
an NT30/NT30C or NT620S/NT620C/NT625C in the functions listed below. The
PT retains full V2 functionality in all functions other than the ones listed below.
Refer to
Appendix C NT30/620 Compatible Mode for more details.

Word configuration and functions of the PT status control area and PT status
notify area
•
Image/library codes
•
Insertion of image/library data into character strings
Data areas in CS1 PCs that were previously inaccessible can be accessed. The
data areas listed below can be accessed (read/written) through a 1:N NT Link
with the CS1 PC. (These areas cannot be accessed through a Host Link connec-
tion.)
All banks in the EM Area, timer completion flags (TU), counter completion
flags (CU), Work Area (WR), task flags (TK), and the HR Area.
You can set the data (numeric values) for multiple words in record units using the
tabular elements on the PT screen, and write these settings in a single operation
to words on the host (i.e., PLC or PT memory) using a touch switch operation on
the PT Unit. Also, multiple words of numeric data can be read from the host in
one operation. In this way, groups of parameter settings can be edited at the PT
Unit, and written to or read from the host.
You can display the brightness and contrast adjustment screen using either the
touch switch or commands from the host, even while the PT is in operation.
