[Design Precautions]
! DANGER
Do not write any data in the “system area” of the buffer memory in the intelligent function
module.
Also, do not use any “use prohibited” signals as an output signal from the programmable
controller CPU to the intelligent function module.
Doing so may cause malfunction of the programmable controller system.
! CAUTION
Do not bundle the control wires and the communication cables with the main circuit and the
power wires, and do not install them close to each other. They should be installed at least 100
mm (3.94 in.) away from each other. Failure to do so may generate noise that may cause
malfunctions.
When changing the operating status of the programmable controller CPU (such as remote
RUN/STOP) from the external device, select "Always wait for OPEN (Communication possible
at STOP time)" for the “Initial timing” setting in the network parameter. The communication line
will be closed when "Do not wait for OPEN (Communications impossible at STOP time)" is
selected and the remote STOP is executed from the external device. Consequently, the
programmable controller CPU cannot reopen the communication line, and the external device
cannot execute the remote RUN.
[Installation Precautions]
! DANGER
Use the programmable controller in an environment that meets the general specifications in the
user’s manual for the CPU module used. Using the programmable controller in any other
operating environments may cause electric shocks, fires or malfunctions, or may damage or
degrade the module.
While pressing the installation lever located at the bottom of module, insert the module fixing tab
into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing
hole as a supporting point.
If the module is not installed properly, it may cause the module to malfunction, fail or fall off.
Secure the module with screws especially when it is used in an environment where constant
vibrations may occur.
Be sure to tighten the screws using the specified torque. If the screws loose, it may cause the
module to short-circuit, malfunction or fall off. If the screws are tightened excessively, it may
damage the screws and cause the module to short-circuit, malfunction or fall off.
Before mounting/dismounting the module, be sure to shut off all phases of external power supply
used by the system.
Failure to do so may cause product damage.
Do not directly touch any conductive part or electronic component of the module.
This may cause the module to malfunction or fail.
