Chapter 1. Outline
The New Satellite JW300 series are high-speed, high-performance programmable controllers for medium
and large-scale control systems. These are high-level models of the JW30H series.

Features
(1) High-speed processing and large memory capacity
- High processing speeds of 33 ns for basic instructions, and 132 ns for application instructions (The
overall processing speed will be approximately 20% faster than our conventional JW30H model.)
- Large, 25 K-word maximum capacity for program memory and 8 M-bytes maximum for file registers
(both approximately 4 times larger than that of the JW30H).
(2) Compatible with memory cards
- Programs and parameters can be backed up on CF cards.
- Extensions to file memory, logging data, etc. can be stored on SRAM cards.
(3) Equipped with a USB port
The JW300 can exchange commands and data with PCs, at high speeds, through its USB port.
(4) Equipped with three ports for communication
There are two ports on the control module (one port on the JW-311CU/312CU) and one port on the I/
O bus expansion adapter (JW-32EA), which can be used for communication. These make it easy to
connect to a control terminal or image sensor camera.
(5) Structured programs / block operation
- You can separate the programs that run on the JW300 into a few blocks so that the PLC can operate
various machines independently, for trial operations and other purposes.
- Each program block can be further separated into sub programs to save programming effort. This will
make it possible to design some programs in parallel. These sub programs can be handled as
standardized modules and can be reused.
(6) Built in faulty equipment diagnosis function
Just program relay numbers and monitor times and the PLC can monitor facilities. This feature makes
for significant savings in writing ladder programs and for detecting errors.
(7) A variety of models
- Ten control module models are available. You can choose the one that best matches your system's
control scale and budget.
- All of the I/O modules and special I/O modules available for the JW20H/30H series can be used with
the JW300. Optional modules for the JW20H/30H also can be used if they are labeled as "compatible
with the JW300."
-A Windows version of our ladder logic programming software, the JW-300SP, is available to support
editing of structured programs.
The JW-15PG hand-held programmer is available to modify and monitor programs on site.
(8) Compatible with various open networks
The JW300 series is Ethernet compatible for communication, FL-net compatible for control, and
DeviceNet compatible for the field. It is also AS-I compatible for sensor applications. These devices
can exchange data with various layers, without any barriers.
