Modbus in China
Modbus-IDA and ITEI Organize Four-City Tour
One year ago, Mr. Jinsong Ouyang, Director of Standardization, Department of
Instrumentation Technology & Economy
(ITEI) , People’s Republic of China, and General Secretary of the National Standardization Technical Committee
on Industrial Process Measurement and Control announced that the Standardization Administration of China had formally
launched three standards for industrial automation in the People’s Republic of China:
Modbus Industrial Automation Network Specification Part 1 – Modbus Application Protocol,
Modbus Industrial Automation Network Specification Part 2 – Modbus Protocol Implementation Guide over Serial Link, and
Modbus Industrial Automation Network Specification Part 3 – Modbus Protocol Implementation Guide over TCP/IP.
Today, 11 companies are formally introducing their Modbus products to audiences in Beijing, Chongqing, Guangzhou, and
Shanghai. From October 21 through October 28, Modbus-IDA members are meeting manufacturers, academics, and govern-
ment officials at events focused exclusively on Modbus. In each city, Modbus-IDA members are showcasing their Modbus
devices at a table-top exhibition and providing special presentations. Member company
ProSoft Technologies
is giving a talk
Extend Your Modbus Communication Connectivity;
is speaking on
The Future Ethernet Technology,
Industrial Networks
is providing a program on
Connecting Modbus to Other Industrial Networks.
ITEI joined Modbus-IDA over the summer and has stepped up its Modbus-related activities, starting with the four-city tour.
Audiences in each city include participants from local universities, manufacturers, and government officials from the industrial
sector. Modbus-IDA will be introduced by Mr. Feng Xiaosheng, head of ITEI and Modbus-IDA Board Director. Other
presentations include an introduction to the ITEI Modbus Conformance Test Laboratory by Test Engineer, Mr. Mei Ke, and
an introduction to basic Modbus technology by Dr. Sun Xin of Northern Jiaotong University. A press conference is also
planned on the tour’s opening day in Beijing.

Modbus Test Program Expands
On October 18, 2005 Modbus-IDA and the Instrumentation Technology & Economy Institute (ITEI) announced the
opening of ITEI’s Modbus Conformance Test Laboratory in Beijing. As part of its expanding Conformance Test Program,
Modbus-IDA is contracting with organizations in locations around the world to offer conformance testing and certification
of Modbus devices. The ITEI laboratory is the first of several planned testing sites worldwide that will make it easier for
companies to get their devices tested closer to home.
Planning for the ITEI lab started in January 2005. With the help of Schneider Elec-
tric engineers, the lab is open today and available to test and certify devices as
conform-ing to the specification for Modbus TCP/IP or Modbus over Serial Line.
Conformance testing is performed with equipment donated by Schneider Electric.
Tested devices are listed on the Modbus-IDA website (,
which features a growing database of Modbus devices for users to search and
identify the right Modbus devices for their applications.
Modbus-IDA is expecting to announce partnerships for Modbus Conformance
Testing in Europe in the near future.

In addition to the table-top exhibitions and company presenta-
tions, Dr. Sun Xin, Northern Jiaotong University, will introduce
basic Modbus technology and Philippe Gelin,
will provide advanced Modbus TCP/IP training. A
Chinese language magazine was produced in conjunction with
the tour with excerpts from past Modbus-IDA newsletters and
introductions to companies participating in the tour.
We look forward to helping our members develop relationships
with Chinese manufacturers and universities over the coming
years. Producing material in Chinese, such as these signs made
for the tour, will make it easier for new customers and new
developers in China to work with Modbus-IDA, and learn about
our activities and opportunities for collaboration.

PCN Introduces iPLC™
Modbus Bridge
Member company
PCN Technology,
this month introduced its iPLC™
Modbus Bridge module for OEM and
ODM customers.
The device
is designed
to provide mission-critical wireless
solutions leveraging existing power
distribution systems.
The iPLC™ Modbus Bridge is an
industrial power communication tech-
nology created for hardened and harsh
environments. It leverages the existing
power distribution system to provide
OEMs with an alternative wireless
solution. Added benefits include
reduction and elimination of wire,
harnesses, bulk, weight, heat, and costs.
PCN’s solutions provide iPLC™
technology, flash program/data self
programming, I2C Master/Slave,
Ethernet, RS-232, RS-485, CAN,
Modbus, DeviceNet, Profibus, USB,
and SPI support on module. Additional
networks are also supported.
The PCN iPLC™ Model EC-2504
supports up to 8 Mbps and is an
embedded open protocol Conducted
Medium Network Convergence Com-
munication System. Current implemen-
tation of the application layer consists
of support for Modbus 2-Wire/4-Wire
RS-232, RS-422, RS-485, or direct TTL
UART interface to a microcontroller
system. Standard baud rates supported
range from 1200 Baud to 250K Baud.
The conducted medium (powerline)
system communicates in the robust
mode on 120 redundant communication
channels to provide maximum reliability
and flexibility.
Multiple socket and network MAC
addressable configurations can also be
supported to provide compatible
communication at up to 4 Mbps on the
conducted medium with the EC2504.
The EC2504 Modbus Convergence
Layer supports RTU, ASCII, and
proprietary iPLC ASCII compression
mode. The iPLC Modbus modes are
independent and interchangeable
regardless of Baud Rate, RTU vs.
ASCII, and physical hardware interface
type. For example, an ASCII Master
Module can speak on RS-232 to a Slave
that is 2-Wire RS-485 in RTU mode (or
any other combination).
Current support for Industrial Ethernet-
IP addressable communication with
programmable multiprotocol support
(e.g., Modbus TCP/IP) are in process.
PCN has focused the company’s
products on increasing security, reliabil-
ity, and performance while reducing
power consumption in control, automa-
tion, computing and converged devices.
PCN products use the proprietary
iPLC™ network protocol allowing
mission critical industrial OEM &
ODM customers the ability to have an
alternative wireless solution without the
reliability and security issues of tradi-
tional wireless in a mission critical
industrial environment.
