14.3.4 Precautions
• If there is a proxy server in the LAN line, deny access from the IP address of the proxy server. If it is allowed,
it will not be possible to prevent access from personal computers that access the proxy server.
• Powering off and on or resetting the CPU module will clear the IP filter settings. When the CPU module is
powered off and on or reset, set the values in the buffer memory (address: 5700
H
to 5721
H
) again and
perform the reinitialization process again.
