PLC communication settings
The IP address and other settings for PLC are set using "Studio5000", "RSLinx", "BOOTP/DHCP", etc. If an IP address has already been set, it is not necessary to set it in BOOTP/DHCP. In addition, when using each tool, it is recommended that you "run as administrator".

2.After startup, a list of devices that do not have IP addresses set is displayed at regular intervals.
3.Double-click the target device to display the setting screen and set a temporary IP address.
