Safety Precautions
This section describes precautions that apply to correct use of devices. Before installing,
operating, maintaining or inspecting devices, always read this manual and all other docu-
ments provided to ensure correct programming. Before using the equipment, familiarize
yourself with equipment details, safety information, and all other precautions.
Installation
• Firmly tighten the Module mounting screws and terminal block mounting screws to
prevent them from loosening during operation.
Loose screws may result in a malfunction of the 260IF Module.
Caution
Unit mounting screws (M4
ユニット取り付けネジ
Phillips screws)
（Ｍ４，プラス）
• Always turn OFF the power supply to the Module before installing it.
• Insert the connectors of the cables that are to be connected to the 260IF Module
and secure them well.
Incorrect insertion of the connectors may result in a malfunction of the 260IF Module.
xi
Wiring
Caution
• Always connect a power supply that meets the given specifications.
Connecting an inappropriate power supply may cause fires.
• Wiring must be performed by qualified personnel.
Incorrect wiring may cause fires, product failure, or malfunctions.
• Do not accidentally leave foreign matter such as wire chips in the Module when wiring.
This may cause fires, failures, and malfunctions.
Safety Precautions
Mandatory
• Always ground the FG terminal to a ground resistance 100 Ω or less.
Failure to ground the 260IF Module may result in electrical shocks or malfunctioning.
Select, separate, and lay external cables correctly.
• Consider the following items when selecting the I/O signal lines (external cables) to
connect the 260IF Module to external devices.
• Mechanical strength
• Noise interference
• Wiring distance
• Signal voltage, etc.
• Separate the I/O signal lines from the power lines both inside and outside the control panel to reduce the influence of noise from the power lines.
If the I/O signal lines and power lines are not separated properly, malfunctioning may result.

Application
WARNING
• Do not touch any Module terminals when the system power is ON.
There is a risk of electrical shock.
Caution
• Do not attempt to modify the 260IF Module programs, force outputs, switch
between RUN and STOP, or performed other similar operations while the 260IF
Module is operating without knowing the direct and indirect consequences of the
operation.
Incorrect programming or operation may damage the equipment or cause an accident.
xiii
Maintenance
WARNING
• Make sure that the polarity of the Module's built-in battery is correct. The battery
must be installed correctly and must not be charged, disassembled, heated, thrown
into fire, or short-circuited.
Improper handling may cause the battery to explode or ignite.
Prohibited
Safety Precautions
• Do not attempt to disassemble or modify the 260IF Module in any way.
Doing so can cause fires, product failure, or malfunctions.
• The customer must not replace any built-in fuses.
If the customer replaces a built-in fuse, the 260IF Module may malfunction or break down.
The built-in fuse must always be replaced by Yaskawa service staff.
xiv
General Precautions
Always note the following to ensure safe use.
• The 260IF Module was not designed or manufactured for use in devices or systems directly related
to human life. Users who intend to use the product described in this manual for special purposes
such as devices or systems relating to transportation, medical, space aviation, atomic power control, or underwater use must contact Yaskawa Electric Corporation beforehand.
• The 260IF Module has been manufactured under strict quality control guidelines. However, if this
product is to be installed in any location in which a failure of the 260IF Module involves a life and
death situation or in a facility where failure may cause a serious accident, safety devices MUST be
installed to minimize the likelihood of any accident.
• Drawings in this manual show typical product examples that may differ somewhat from the product
delivered.
• This manual may change without prior notice due to product improvements and specification
changes or for easier use. We will update the manual number of the manual and issue revisions
when changes are made. The revision number of the revised manual appears on the back of the
manual.
• Contact your nearest Yaskawa sales representative or the dealer from whom you purchased the
product and quote the manual number on the front page of the manual if you need to replace a
manual that was lost or destroyed.
• Contact your nearest Yaskawa sales representative or the dealer from whom you purchased the
product to order new nameplates whenever a nameplate becomes worn or damaged.
• Products modified by the customer are not covered by the Yaskawa warranty, nor does Yaskawa
assume any liability for injury or damage that may result from such modifications.

System Configuration
1.1 Outline of Configuration and Functions
The DeviceNet is a multivendor field network. DeviceNet specifications are controlled by the
ODVA（Open DeviceNet Vendor Association, Inc.).
The 260IF Module connects to a multivendor DeviceNet system and works as either a
DeviceNet Master or Slave.
Refer to the DeviceNet specifications published by the ODVA for information on the
DeviceNet.
1.1.1 System Configuration
The 260IF Module is a communications interface used to connect MP900 Machine Control-
lers to a DeviceNet network. Using the 260IF Module enables communications between
MP900 Machine Controllers, other controllers, sensors, actuators, and other devices manu-
factured by other companies.
The 260IF Module can be connected to the DeviceNet as a Master or Slave.

∗ 1. The 260IF Module is offline for the two seconds from the completion
of the indicator test after startup through the completion of the MAC

∗ 2. When the network power supply is OFF, the 260IF Module automati-
cally resets as specified in the DeviceNet specifications even if a busoff error occurs. At the same time, the NS indicator will light red for a
moment and then go OFF again immediately. After power has been
restored to the network, the green NS indicator will start flashing
(online but not connected).
The following diagram shows the indicator test sequence that is performed immediately
after the power is turned ON. Check the ON and OFF status of these indicators for any mal-
functions. About 1 second is required for this test.

Configuration Elements
The network is configured from the following elements.
Node Node
Terminating
resistance
Nodes
A node is either a slave that connects to external I/O, or the Master, which manages the I/O
of the slaves. There are no restrictions on the locations of the Master or Slaves. Any node in
the figure above can be the Master or a Slave.
Trunk Line and Drop Lines
A cable with a terminator on each end is the trunk line. Any cable branching from the trunk
line is a drop line.
Connection Methods
A node is connected using the T-branch method or multi-drop method. A T-Branch Adapter
is used to connect a node with the T-branch method. A node is directly connected to the
trunk line or a drop line with the multi-drop method. Both T-branch and multi-drop methods
3-2
3.1
Network Configuration
can be used together in the same network, as shown in the figure above.
Terminators
Both ends of the trunk line must connect to terminating resistance to decrease signal reflec-
tion and ensure stable network communications.
Communications Power Supply
The communications connectors of each node must be provided with communications
power supply through the communications cable for DeviceNet communications. Commu-
nications power supply, internal circuit power supply, and I/O power supply must all be pro-
vided separately.
INFO
1 Use only DeviceNet cables as communications cables.
2 Always connect terminators to both ends of the trunk line.
3 Do not connect lightning arresters or any devices to the network other than the 260IF Module and
DeviceNet-conforming products.
