Typical Distributed Control Structure
From simple stand alone systems and basic
AS-Inter face networks to Ethernet based net
-
works and even Global networks based on
Remote Telemetry Technology, Mitsubishi h as
the answers.
Here is an overview of some of the networks
Mitsubishi provides:
Ethernet
The standard network for business operations
is Ethernet. There are various options available,
10 Mb rate is the most common, but many new
installations are operating at 100 Mb transfer
rate. Ethernet c ould be termed an OPEN net-
work owing to its absolute acceptance within
the IT environment and the sheer number of
providers of Ethernet based IT products.
Ethernetcanbeusedwithvariousdifferent
protocols. The most popular protocol used is
TCP/IP which most people use every single
time they log on to the Internet.
Modbus/TCP
This protocol is widely accepted as a
manufacter neutral, defacto standard for auto-
mation. Modbus/TCP is widely supported by
PLC manufac tures, I/O vendors and by many
other automation technology.
CC-Link (Process Solution/Fieldbus)
From PLCs and Motion Controllers to HMIs
and Robots, CC-Link encompasses all areas of
Mitsubishi automation produc ts. Although
CC-Link is an open network it is still controlled
by M itsubishi and the CC-Link Partner
Associztion (CLPA), which allows them to
implement a strict control/testing regime of
any product which connect onto CC-Link.
This helps to guarantee and preser ve the
CC-Link network integrity.
Profibus (Process Solution/Fieldbus)
Profibus offers users the option to mix devices on
the network, ranging from simple remote I/O sta-
tions and inverter stations through to more com-
plex HMIs, data logging devices and PLCs.
DeviceNet (Process Solution/Fieldbus)
DeviceNet is an emerging Open vendor network.
The DeviceNet network is based on the Controller
Area Network ( CA N)serial bus system. DeviceNet
is a producer/consumer operation where
peer-to-peer or master/slaveconfigurations are
possible.
CANopen
Cost effec tive network communications with
fault-resistant network structure where compo
-
nents from different manufac turers can be inte
-
grated quickly and easily.
AS-Interface (Actuator - Sensor - interface)
This network is well supported by sensor manu
-
facturers. AS-Inter face can be used both with
standard sensors and with special AS-Interface
sensors. The dedicated AS-Interface sensors are
typically more expensive than standard ones
but do offer additional diagnostic functions
and automatic configuration.
MELSECNET/H
This is Mitsubishi's own dedicated, high perfor-
mance network. MELSECNET/H can have either
coaxial bus or a dual loopcable configuration. This
offe r shighnetwor kavailability, as cable breaks are
automatically detected and the active communi-
cation channel is automatically re-routed around
the suspected break. Another major feature of the
MELSECNet/H network is the ability to operate a
floating master system. This allows other PLC’s on
the network to take up the position of network
master should a fault develop with the currently
selected master.
