■General Requirements for Using FA-M3 Controllers
●Avoid installing FA-M3 controllers in the following locations:
• Where the instrument will be exposed to direct sunlight, or where the operating tem-
perature is outside the range 08to 558C.
• Where the relative humidity is outside the range 10 to 90%, or where sudden tempera-
ture changes may occur and cause condensation.
• Where corrosive or inflammable gases are present.
• Where the instrument will be exposed to direct mechanical vibration or shock.
●Securely tighten screws:
• Securely tighten module mounting screws and terminal screws to avoid problems
such as faulty operation.
●Securely fasten connectors of interconnecting cables:
• Securely fasten connectors of interconnecting cables, and check them thoroughly
before turning on the power.
●Interlock with emergency-stop circuitry using external relays:
• Equipment incorporating the FA-M3 controllers must be furnished with emergency-
stop circuitry that uses external relays. This circuitry should be set up to interlock
correctly with controller status (stop/run).
●Ground FA-M3 controllers to an independent Japanese Industrial Standard
(JIS) Class 3 Ground:
• Avoid grounding the FG terminal of the FA-M3 controller to the same ground as high-
voltage power lines. Ground the terminal to an independent JIS Class 3 ground
(ground resistance up to 100 Ω).
●Observe countermeasures against noise:
• When assigning inputs/outputs, the user should avoid locatingAC-supplied I/O mod-
ules in the vicinity of the CPU module.
●Keep spare parts on hand:
• Stock up on maintenance parts, including spare modules, in advance.
●Discharge static electricity before operating the system:
• Because static charge can accumulate in dry conditions, first touch grounded metal to
discharge any static electricity before touching the system.
●Never use solvents such as paint thinner for cleaning:
• Gently clean the surfaces of the FA-M3 controllers with a piece of soft cloth soaked in
water or a neutral detergent.
• Do not use solvents such as paint thinner for cleaning, as they may cause deforma-
tion, discoloration, or malfunctioning.

vi
<Toc> <Ind> <Rev> <Preface>
IM 34M6H28-01E 1st Edition : Feb.01,1999-00
●Avoid storing the FA-M3 controllers in places with high temperature or
humidity:
• Since the CPU module has a built-in battery, avoid storing it in places with high tem-
perature or humidity.
• Since the service life of the battery is drastically reduced by exposure to high tem-
peratures, so take special care (storage temperature can be from -208to 758C).
●Always turn off the power before installing or removing modules:
• Turn off power to the power supply module when installing or removing modules,
otherwise damage may result.
●When installing ROM packs and changing switch settings:
• In some modules you can remove the right-side cover and install ROM packs or
change switch settings. While doing this, do not touch any components on the printed-
circuit board, otherwise components may be damaged and modules fail.

1. Overview
The F3LD01-0N DeviceNet Scanner Module (hereafter referred to as this module) is a
module for connecting to DeviceNet.
■What is a DeviceNet?
DeviceNet is an open field network and is mainly used in manufacturing equipment or in
production lines. In a multi-vendor environment, a wide range of devices, ranging from
sensors and actuators to advanced equipment which is compatible with DeviceNet, can be
connected.
As the specifications of DeviceNet are open and licensing is not required, many manufac-
turers, both in Japan and overseas, are developing new devices which, when connected
with DeviceNet, allow exchanges of I/O data. Overseas service has also become possible.
Further, many types of I/O communications and message communications are supported.
Decentralized control with multi-master systems is also possible now.
Amaximum of 64 machines (masters + slaves) can be connected to DeviceNet. The
maximum data rate is 500 kbps and the maximum trunk line distance is 500 m (when the
data rate is 125 kbps). Thus, with these special characteristics of high connectability to
many stations, a high data rate and a long distance, DeviceNet can be used in a wide range
of applications. Wiring can be done effectively by freely combining theT-branching method
and daisy chain method, with no wastage.
Each equipment type is defined by a device profile (specifications which define the opera-
tion of the equipment). Equipment is built according to these profiles, thus resulting in the
compatibility and interchangeability of the equipment.

■Features of this module
This module has the master functions of DeviceNet. Using this module, you can exchange
I/O data periodically with other connected devices and exchange message data like param-
eters and status.
The following are the main features of this module.
• Amaximum of 63 slave machines can be connected.
• Data rate is 125/250/500 kbps.
• Supports an I/O communication function which regulates and controls I/O data of
16,000 points (input 8,000 points; output 8,000 points).Anything from small-scale I/O
data to multiple-point analog data and information data can be handled in real time.
• Amessage communication function is supported. If required, the exchange of mes-
sage data like parameters and status is also possible. Therefore, the time required for
system configuration is reduced, and maintenance as well as calibration becomes
easier.
• Operation in a multi-master environment with decentralized control is also possible.
• 16 modules of this kind can be installed in a single FA-M3. It is easy to manage mul-
tiple-point I/O data and to add new lines.
• The transmission time interval of I/O data can be set for every 5 msec.Thus, it is
compatible even with a slow-responding slave.

2. Overview of DeviceNet
An explanation of the functions which are supported by this module and which are related
to the DeviceNet specifications is given here.

The elements of the network configuration are explained below.
• Node
Adevice (equipment) that is connected to DeviceNet is called a node. Anode can be either
a master, which collects and distributes data, or a slave, which outputs and inputs data
according to the instructions received from the master.
There are no restrictions on the arrangements or maximum number of devices that can be
connected to the master of each of the slaves. Amaximum of 64 devices can be freely
connected (without arrangement restrictions).
An address from 0 to 63, called MACID (MediaAccess Control Identifier), is assigned to
each node. In this manual, these addresses are called node addresses.

• Cable
Five special purpose cables (2 signal lines, 2 power supply lines, and 1 SHIELD cable) are
used. There are 2 types of cables, namely, thick cables and thin cables .
• Trunk Line
Terminating resistors are attached at both ends of this cable. Both thick and thin cables can
be used. They can also be used together.
For a thin cable, the maximum network length is 100 m. In the case of thick cables, the
length limits depends on the data rate (see Table 2.1).
• Drop line
This is a branch cable from the trunk line and normally, thin cables are used for this pur-
pose.
The length (the distance from the point of branching from the trunk line to the end of the
drop line) of a drop-line cable should be 6 m or less. (There are no minimum distance
limits.) Generally, the total drop-line length depends on the data rate (see Table 2.1).

100 m 6 m
156 m
250 kbps 250 m 78 m
500 kbps 100 m 39 m
T0201.EPS
• Connection Method
There are 2 methods of wire connection, the T-branching (using the T-branching tap) and
multiple-node daisy-chain methods. In a trunk line/ drop line, both methods can be com-
bined.
• Terminating Resistor
Terminating resistors (121V) are attached to both ends of a trunk line. This reduces the
reflection of signals and stabilizes communication.
In this module, there is a built-in terminating resistor. Therefore, when connecting the trunk
line using the daisychain method, you can turn on the terminating resistor setting switch
and use the built-in terminating resistor. In other connection methods, please turn the
switch off so that the built-in terminating resistor is not used.
• Network Power Supply
Out of the 5 special-purpose cables, two are for the 24 V DC network power supply. It is
necessary to supply power to each node of the network using the cables. If a single net-
work power supply source is used in a network, you can connect the power supply directly
to the trunk line. However, if multiple power supply sources are to be used in the network, it
is necessary to use special-purpose power supply taps.

2.2 I/O Communications (I/O Slave Message)
This is a communication function which allows the exchange of control information (I/O
data) between the master and a slave in real time.
This module supports the following two types of I/O communications protocols of
DeviceNet.
Polling..........Sends polling instructions containing output data from the master to a
specified slave; the master then receives a response containing the input
data from the slave
(1 : 1 communication).
Bit Strobe.....Multicasts (broadcasts) Bit Strobe request instructions from the master to
multiple slave systems and receives a response with input data from each
slave. Acommunication request that can be transmitted to multiple slaves
at a time (1:N communications) will improve network throughput. However,
this is possible only in the case of slave systems with input data of less than
8 bytes.
In this module, transmission of I/O communications requests is cyclic. This period (trans-
mission time interval) can be specified for all the slaves in a batch in 5 ms intervals.

2.3 Message Communications (Explicit Peer-to-
Peer Message)
This is a function for setting and reading parameters, controlling and managing operations
and exchanging information between nodes (1: 1) when necessary. In this module, it is
possible to send a service request to other nodes (master and slaves) using the explicit
messages defined in DeviceNet.
