• The PC outputs may remain ON or OFF due to deposition or burning of the
output relays or destruction of the output transistors. As a countermeasure for
such problems, external safety measures must be provided to ensure safety in
the system.
• When the 24-VDC output (service power supply to the PC) is overloaded or
short-circuited, the voltage may drop and result in the outputs being turned
OFF. As a countermeasure for such problems, external safety measures must
be provided to ensure safety in the system.
Execute online edit only after confirming that no adverse effects will be caused
by extending the cycle time. Otherwise, the input signals may not be readable.
Confirm safety at the destination node before transferring a program to another
node or changing contents of the I/O memory area. Doing either of these without
confirming safety may result in injury.
Tighten the connector screws for the backup power supply to the torque speci-
fied in this manual. The loose screws may result in burning or malfunction.

• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified in
the specifications.
• Locations subject to condensation as the result of severe changes in tempera-
ture.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
Take appropriate and sufficient countermeasures when installing systems in the
following locations:
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
The operating environment of the Controller Link Support Board for PCI Bus or
the computer can have a large effect on the longevity and reliability of the sys-
tem. Improper operating environments can lead to malfunction, failure, and oth-

the computer. Be sure that the operating environment is within the specified
conditions at installation and remains within the specified conditions during the
life of the system.
