Reduce Maintenance Unit Stocks
Software Compatibility with CS1-series PLCs
The CJ1-series PLCs can be used for anything from
small-scale to large-scale applications, helping to
reduce the quantity of maintenance Units stocked
for unexpected troubles or system expansion.
Built-in Flash Memory (Standard Feature)
Built-in Comment Memory
When the user program or parameter area data is transferred to
the CPU Unit, it is automatically backed up in flash memory in the
CPU Unit. (The flash memory data is automatically restored to the
working memory in the CPU Unit when the power supply is turned
ON.) This enables battery-free
operation without using a Memory Card.
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.

CJ-series architecture is
100% compatible with
the CS-Series. User
programs and other
software resources can
be shared to make
standardizing software
easier for all levels of
the system.

The comments can be stored in either of three locations: a) Memory Card, b) EM file memory, or c) Comment memory (added with this unit version). Select the
location to store the comments in the user settings.
(Unit version 3.0 or later and CX-Programmer Ver. 5.0 or higher are required.)
