Observe the following precautions when using the CX-Integrator.
General Communications Precautions
• Do not turn OFF the power to the PLC or disconnect the cable connecting
the PLC when the CX-Integrator is online with the PLC. Doing so may cause
the computer running CX-Integrator to malfunction.
• Before changing the operating mode, always confirm that doing so will not
adversely affect system operation.
• Always check the operation of parameters sufficiently before using them for
actual system operation.
• Confirm that resetting CPU Bus Units and Special I/O Units will not
adversely affect system operation before resetting these Units.
• Use only the specified communications cables.
• Do not extend connection distances beyond the ranges given in the
specifications.
• Take appropriate measures to ensure that the specified power with the rated
voltage and frequency is supplied. Be particularly careful in places where the
power supply is unstable. An incorrect power supply may result in
malfunction.
• When installing the PLC, ground to 100Ω min.
• Install external breakers and take other safety measures against
short-circuiting in external wiring. Insufficient safety measures against
short-circuiting may result in burning.
• Check all wiring and switch settings to be sure they are correct before
turning ON the power supply.
• Check the user programming (e.g., the ladder program) for proper execution
before actually running it on the PLC. Not checking the program may result
in unexpected operation.
