met.
Operations are also possible for conditions set for memory in the PT and to
manipulate memory in the PT.
You can register up to 16 languages and corresponding character strings for
each part in advance and then change all registered parts at the same time
using a function switch or a command from the PLC.
This allows you to switch the language during operation or switch the labels in
the same language.
You can constantly back up specified words from the PLC in SRAM in the PT.
This allows you, for example, to back up memory areas that are not held in the
PLC when using a CP1E PLC without a battery.
You can also back up the specified data from the internal memory in the PT.
You can set a password of up to eight alphanumeric characters for transferring
screen data from the NV-Designer to an NV-series PT, to prevent screen data
from being transferred when anyone other than the administrator attempts to
read PT screen data.
You can set a password for each operation level of a part to restrict displays
and operations.
Security passwords are managed according to operator level.
The screens can be transferred using an SD memory card even if the PT can-
not be connected to the NV-Designer.
Project data can be transferred directly by using SD memory cards.
The NV3W-V1, NV4W or NV3Q can connect an OMRON EJ1 Temperature
Controller using Modbus-RTU. The EJ1 Temperature Controllers are con-
nected using RS-485 with the PT as the master. Up to 31 Temperature Con-
trollers can be connected.
In addition to the previous monochrome display with two shades of gray, you
can now also select a monochrome display with eight shades of gray for
improved screen display quality.
