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
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
If synchronous unit operation is being used, perform online editing only
after confirming that an increased synchronous processing time will not
affect the operation of the main and slave axes.
Caution
Confirm safety sufficiently before monitoring power flow and present value
status in the
Ladder Section window or when monitoring present values in
the Watch window. If force-set/reset or set/reset operations are
inadvertently performed by pressing short-cut keys, the devices connected
to Output Units may malfunction, regardless of the operating mode of the
CPU Unit.
Caution
Caution is required when connecting peripheral devices, such as a
personal computer, to the PLC when Units with non-isolated power
supplies, such as the CS1W-CLK12/CLK52(-V1), that are connected to an
external power supply are mounted to the PLC. If the 24-V side is grounded
on the external power supply, a short will be created if the 0-V side of the
peripheral device is grounded. When connecting peripheral devices, either
ground the 0-V side of the external power supply or do not ground the
external power supply at all.
