WARNING
●
To set a refresh device in the network parameters, specify the device Y for the remote output (RY)
refresh device.
If a device other than 'Y', such as 'M' and 'L', is specified, CPU module holds the device status as is
even after the module status is changed to STOP.
WARNING
●
To prevent the malfunction of the programmable controller system due to harmful e-mails, take
preventive measures (such as antivirus measures) so that the mail server for Ethernet module does
not receive harmful e-mails.
WARNING
●
Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●
During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
●
After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size. Design circuits so
that the entire system will always operate safely, regardless of the time.
●
Do not power off the programmable controller or do not reset the CPU module while the settings are
being written. Doing so will make the data in the flash ROM undefined. The values need to be set in
the buffer memory and written to the flash ROM again. Doing so may cause malfunction or failure of
the module.
●
When changing the operating status of the CPU module from external devices (such as remote RUN/
STOP functions), select "Do Not Open in Program" for "Open Method Setting" in the module
parameters. If "Open in Program" is selected, an execution of remote STOP causes the
communication line to close. Consequently, the CPU module cannot reopen the communication line,
and the external device cannot execute the remote RUN.
