Operating Environment Precautions 4
!Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the operation manual. The loose screws may result in
burning or malfunction.
4 Operating Environment Precautions
!Caution Do not operate the control system in the following locations:
• 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 tem-
perature.
• 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.
!Caution 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.
!Caution The operating environment of the PLC System can have a large effect on the
longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi-
tions at installation and remains within the specified conditions during the life
of the system.
5 Application Precautions
Observe the following precautions when using the PLC System.
• You must use the CX-Programmer (programming software that runs on
Windows) if you need to program more than one task. A Programming
Console can be used to program only one cyclic task plus interrupt tasks.
A Programming Console can, however, be used to edit multitask pro-
grams originally created with the CX-Programmer.
• There are restrictions in the areas and addresses that can be accessed in
I/O memory of the CS-series CS1 CPU Units when using the C200H Spe-
cial I/O Units in combination with the following functions.
• There are restrictions in data transfer with the CPU Unit when pro-
gramming transfers inside an ASCII Unit using the PLC READ, PLC
WRITE, and similar commands.
• There are restrictions in data transfer with the CPU Unit for allocated
bits and DM area specifications (areas and addresses for source and
destination specifications).
