11. Program Example
This section describes a program in the PLC for the configuration shown in "11.2 System
configuration".
In this example, the I/O numbers are assigned automatically in the CONFIG mode.
The specification as reserved station and the detailed remote station information are not
changed. Parameter settings and programs for assigning the I/O numbers are not necessary.
DESIGN PRECAUTIONS
• When a remote module fails, outputs may randomly become ON or OFF, therefore an
external monitoring circuit that will monitor any input signals that could cause a serious
accident is necessary.
DESIGN PRECAUTIONS
• Do not bind control cables and connection cables to CC-Link/LT together with power
cables.
Keep control cables and connection cables to CC-Link/LT away from major circuits and
power cables by 100 mm (3.93") or more.
There may be malfunction due to noise interference.
• Install the FX
2N
-64CL-M in such away that no force is applied to connectors on the
CC-Link/LT interface and the connection cables to CC-Link/LT.
If any force is applied, wire breakage and failure may occur.
INSTALLATION PRECAUTIONS
• Use the FX
2N
-64CL-M in an environment with the general specifications described in this
manual.
If the FX
2N
-64CL-M is used in any other environment, electrical shock, fire, malfunction,
product damage or product deterioration may occur.
• Do not touch the conductive area of the FX
2N
-64CL-M.
If the conductive area is touched directly, the FX
2N
-64CL-M may malfunction or fail.
• Shut down all power supplies before attaching/removing the FX
2N
-64CL-M to/from the
panel.
If the power is not disconnected from all sources, the FX
2N
-64CL-M may fail or
malfunction.
• Securely fix the FX
2N
-64CL-M with DIN rail or mounting screws. When using mounting
screws, securely tighten them within the specified torque range.
(Refer to Subsection 5.1.3.)
If the screws are too loose, the module may detach from its installed position, short
circuit, or malfunction. If the screws are too tight, the screws may be damaged, which
may cause the module to detach from its installed position or short circuit.
• Install the FX
2N
-64CL-M on a flat surface.
If the installation surface is not flat, an excessive force may be applied on the PCBs,
leading to nonconformity.
