1. Introduction
RC620 Option Fieldbus I/O Rev.8 1
1. Introduction
1.1 Overview of Fieldbus I/O
The Fieldbus I/O option is an integrated I/O system that supports the following Fieldbuses:
DeviceNet
PROFIBUS DP
EtherNet/IP
CC-Link
PROFINET
Fieldbus is a standard of signal communications between field devices operating in a
factory (sensor, actuator, robot controller, etc.) and controller (PLC or robot controller)
using serial communications. Compared to signal communications using analog signals,
Fieldbus has the following features:
Access to signals from multiple devices and multiple data from each device using one
cable.
Precise signal transmission since there is no need for A/D conversion and D/A conversion.
Less wiring costs, including signal relay board costs and installation area due to several
dozen (or a hundred) devices connected on one Fieldbus.
More flexible modification and expansion of a system because multiple devices are simply
added to one Fieldbus without additional wiring.
Slave devices can transmit self-diagnostics information.
Master Devices
RS-232c RS-232c Fieldbus
Sample Parallel Connection Sample Fieldbus Connection
Master Devices
The Fieldbus master function can be added to the RC620 robot controller by installing the
Fieldbus master board. Each type of Fieldbus supports the following boards.
DeviceNet master board
PROFIBUS-DP master board
EtherNet/IP master board
You can install one Fieldbus master board per controller. To use the Fieldbus master I/O,
the Fieldbus master option of the EPSON RC+ software options key must be enabled.

1. Introduction
2 RC620 Option Fieldbus I/O Rev.8
You can also add the Fieldbus slave function by installing the Fieldbus slave board. Each
type of Fieldbus supports the following boards.
DeviceNet slave board
PROFIBUS-DP slave board
EtherNet/IP slave board
CC-Link slave board
PROFINET slave board
You can install one Fieldbus slave board per controller.
One Fieldbus master board and one Fieldbus slave board can be used together regardless
of Fieldbus types.
1.2 DeviceNet
1.2.1 Overview of DeviceNet
DeviceNet is a fieldbus network that provides easy interconnection between control
devices (PLC, PC, sensor, actuator, etc.).
DeviceNet was developed by Allen-Bradley as an open communication standard to
connect various field devices (sensor, actuator, robot controller, etc.). Because of the open
communication standard, DeviceNet users can easily construct a multi-vendor system with
various devices developed around the world.

1.2.2 Features of DeviceNet
Reduced Wiring
Compared with parallel wiring, DeviceNet employs a dedicated 5-wire cable (signal wires
and power wires) which substantially reduces the number of necessary wires, wiring time
and cost.
Detachable communication connectors provide you with simple wiring between nodes and
easy network separation or reconstruction.
Specified environment-resistance cables allow you to construct an environment-resistant
system at low cost.

1. Introduction
RC620 Option Fieldbus I/O Rev.8 3
Open Standard (Multi-vendor)
Due to an open communication standard, various devices from many manufacturers are
available. Standardized communication connectors provide you with easy network
reconstruction.
Maintenance spare parts stored on site (factory, etc.) can be reduced because different
manufacturers’ devices can be used in case of a breakdown. Similar products are available
around the world due to a global standard DeviceNet.
Numbers of Inputs/Outputs
Using a Fieldbus master board, you can control 1,024 inputs (128 bytes) and 1,024 outputs
(128 bytes).
Also, using a Fieldbus slave board, you can exchange 256 inputs (32 bytes) and 256
outputs (32 bytes) with a master.
Communication Types
There are two types of messaging connections: I/O messaging connection and Explicit
messaging connection. I/O messaging connection includes the following 4 methods
explained below:
Polling : First, a master device sends output data to a slave device and then the
slave device responds. Data is normally exchanged in every
communication cycle. The communication frequency can be changed
by setting. This connection type is the most often used.
Strobe : First, a master device requests slave devices to send data with
multicast messages, and then, each slave device responds individually.
Data from many sensors on the system can be effectively gathered.
When the master does not receive responses from all requested slave
devices, a timeout error occurs.
Change Of State: A device sends data whenever it changes. Signals for device diagnosis
are sent regularly in the background. This connection type is useful for
remedying DeviceNet communication traffic.
Cyclic : A slave device transfers data regularly according to its internal timer.
This connection type is typically used for communicating with a
temperature controller. The data transfer frequency is defined by
master configuration.
For Change of State and Cyclic, the ACK which verifies communication completion
can be disabled by setting. However, never disable the ACK since communication
errors cannot be detected.
