Remote Maintenance
1. Program or monitor a remote
PLC via a modem connection.
2. Program or monitor a
network PLC via a Host Link
connection.
3. Send e-mail for errors from
PLCs connected to Ethernet.

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.

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.

Use a password to
prevent reading of
only task 2.

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.

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.

Prevent Information Leaks from
PLCs (for CPU Unit Ver. 2.0 or Later)
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.

Write Protection from a Specific
Node over the Network
(for CPU Unit Ver. 2.0 or Later)
You can now stop specific nodes from
writing over the network. By preventing
unintentionally writes to the PLC while
monitoring data over the network, you
can prevent potential problems.

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.
● CV-CS address conversion instruction to
convert programs designed for the
CVM1/CV that include internal I/O memory
addresses.
● C200HX/HG/HE: Region comparison (ZCP
and ZCPL) instructions.

Replace Malfunctioning Units
without Turning OFF the Power
(Online Unit Replacement)
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.)

Store All I/O Comments, Symbol Names, Rung Comments, and Other
Information in CPU Unit Comment Memory (See note.) (Unit Ver. 3.0 or later)
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.
Note: CX-Programmer Ver. 5.0 or higher required.
