Safety Precautions
This section describes precautions that apply to ladder programming. Before programming,
always read this manual and all other documents provided to ensure correct programming.
Before using the equipment, familiarize yourself with equipment details, safety information,
and all other precautions.
Handling
Installation
• Do not subject the product to halogen gases, such as fluorine, chlovine, bromine, and
iodine, at any time even during transportation or installation.
Failure to observe this caution may cause damage or failure of the product.
• Firmly tighten the Module mounting screws and terminal block mounting screws to pre-
vent them from loosening during operation.
Loose screws may result in a malfunction of the MP920.
• 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 MP920 Modules and
secure them well.
Incorrect insertion of the connectors may result in a malfunction of the MP920.
CAUTION
CAUTION
Module mounting screw
(Use an M4 Phillips screw driver.)

viii
Wiring
• 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 electrical shocks.
• Do not accidentally leave foreign matter such as wire chips on the Mounting Base or in
the Module when wiring.
This may cause fires, failures, and malfunctions.
CAUTION
• Always ground the FG terminal to a ground resistance 100Ωor less.
Failure to ground the MP920 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 MP920 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.

ix
Application
Maintenance
• Do not touch any Module terminals when the system power is ON.
There is a risk of electrical shock.
WARNING
• Do not attempt to modify the MP920 programs, force outputs, switch between RUN and
STOP, or perform other similar operations while the MP920 is operating without know-
ing the direct and indirect consequences of the operation.
Incorrect programming or operation may damage the equipment or cause an accident.
CAUTION
• 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.
WARNING
• Do not attempt to disassemble or modify the MP920 Modules 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 MP920 Module may malfunction or break down.
The built-in fuse must always be replaced by Yaskawa service staff.
PROHIBITED

1.1 Overview
This section describes the Communications Module that are provided as options in the MP920
and outlines their specifications.
1.1.1 Communications Modules
The following three Communications Modules are provided for the MP900-Series building-
block Machine Controllers:
• The 215IF Realtime Core Network Interface Module with link transmission functions.
This is a special Yaskawa network.
• The 217IF Serial Interface Module with RS-232C and RS-422/485 ports
• The 218IF Ethernet Interface Module with 10Base-T port
The following illustration lists the name, a brief description, and the appearance of each
Communications Module.
Table 1.1 Communications Modules
Module Name Overview Appearance
215IF A Yaskawa Realtime Core Network Interface Mod-
ule equipped with one communications line and
having a transmission speed of 4 Mbps.
A relay function can be used to access Machine
Controllers that are not directly connected to the
same network.
217IF A Serial Interface Module equipped with two RS-
232C lines and one RS-422/485 line.
218IF An Interface Module for the international Ethernet
standard equipped with one communications line.
Communications are easily achieved with control-
lers manufactured by other companies, personal
computers, workstations, and other devices.

RS-232C ports are standard features on MP920 and MP930 CPU Modules and can be used for commu-
nications even without an optional Communications Module. While some functions of the communi-
cations protocols for these Modules differ, the RS-232C ports are almost the same as those for the
217IF.
