In addition to applying read protection
functions to the user program area and
tasks, you can also protect against the
transfer of user programs to a Memory
Card.This prevents leaks of proprietary
information by completely protecting
against the reading of programs inside
the PLC.
When an I/O Unit, a Special I/O Unit, or
a CPU Bus Unit is malfunctioning, it is
now possible to replace the faulty Unit
while the system continues operating.
This is particularly effective for systems
that cannot be stopped when a problem
has occurred in another part of the
system.
(This function requires a CS1D-CPU S CPU
Unit, a CS1D-BC082 or CS1D-BI092 Backplane,
and a CS1D-PA207R or CS1D-PD024 Power
Supply Unit.)

Memory Cards for Data File
Management
User programs, I/O memory, or system
parameters can be converted to
Windows-based files and stored in
Memory Cards or in EM file memory in
the CPU Unit. It is also possible to
automatically read the user program
and other data from the Memory Card
to the CPU Unit at startup, replacing
ROM operation. Change programs on-
site using only a Memory Card and
Programming Console, or use Memory
Cards to store symbol tables or I/O
comments. Connecting a Programming
Device allows monitoring operations
with ladder programs with comments.
It is also possible to save and read data
such as DM data to a Memory Card
during operation, and the Memory
Cards are ideal for operations such as
saving quality data and reading recipes.
Internal Flash Memory-based
Battery-free Operation
Flash memory (non-volatile memory) is
built into the new CS1's CPU Unit. User
programs and system parameters (e.g.,
PC Setup and data link tables) are
automatically saved to this flash
memory. This means that the new CS1
can operate without a Memory Card
and battery.
Boost Program Security
by Keeping Part of It Hidden
(for CPU Unit Ver. 2.0 or Later)
You can prevent access to special tasks
by requiring the user to have a
password to read them.
This allows you to hide crucial parts of
the program.
By applying write protection, you can
also prevent a user from inadvertently
writing over the hidden part of the
program. This provides additional
protection for your program.
Easy Replacement of Existing
Models
Programs designed for existing models
(C200HX/HG/HE, CVM1, or CV-series
PLCs) using the CX-Programmer can be
converted for use with the new CS1.
The following functions are available to
make the conversion to the new CS1
even easier.

Store All I/O Comments, Symbol Names, Rung Comments,
and Other Information in CPU Unit Comment Memory
When downloading projects, the
Memory Card, EM file memory, or
comment memory (in the CPU Unit's
flash memory) can be selected as the
transfer destination for I/O comments,
symbol names, rung comments, and
other data. This enables data such as
I/O comments, symbol names, and
rung comments to be stored in the CPU
Unit's internal comment memory when
a Memory Card or EM file memory are
both not available. (PLC models: CS/CJ-
series with unit version 3.0 or later
only.)
