Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so
may result in malfunction, fire, or electric shock.
WARNING
Do not touch the Power Supply Unit while power is being supplied or
immediately after power has been turned OFF. Doing so may result in electric
shock.

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.
Caution
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.
Caution
Tighten the screws on the terminal block of the AC Power Supply Unit to the

Caution
The operating environment of the PC System can have a large effect on the lon-
gevity and reliability of the system. Improper operating environments can lead to

Application Precautions
Observe the following precautions when using the PC System.
•
You must use the CX-Programmer (programming software that runs on Win-
dows) 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 Program-
ming Console can, however, be used to edit multitask programs originally
created with the CX-Programmer.
