WARNING
● When data link becomes faulty, the operation of communication faulty station
vary depending on its data link type. Configure an interlock circuit in the
sequence program using the communication status information so the safety
of the entire system is always maintained.
Refer to the manual of each data link for how to confirm communication
faulty stations and the operation status during a communication error.
CAUTION
● Do not bunch the control wires or communication cables with the main circuit
or power wires, or install them close to each other.
They should be installed 100mm (3.9 in) or more from each other.
Not doing so could result in noise that would cause malfunction.
WARNING
● Use the programmable controller in an environment that meets the general
specifications contained in this manual. Using this programmable controller
in an environment outside the range of the general specifications could result
in electric shock, fire, malfunction , and damage to or deterioration of the
product.
● Tighten the module installation screws within the range of specified torque. If
the module installation screws are loose, it may result in short circuits, fire or
malfunction. Tightening the module installation screws too far may cause
damages to the screws and /or the module, resulting in fallout, short circuits
or malfunction.
● Do not directly touch the module's conductive parts. Doing so could cause
malfunction or trouble in the module.
● Securely install the connectors for the drive unit and peripheral devices into
the module connectors until a clicking sound comes. Improper installation
may cause false contact, resulting in false input and output.
● When the drive unit and peripheral device are not connected, be sure to
attach the connector cover. Failure to do so may cause malfunction.
