DM[100] = 255
	DM[101] = 255

	DM[103] = 0
	SET_WIFI_SUBNET 100	' Set the subnet mask to 255.255.255.1

	RESTART 		' Reboot the PLC

• To change the subnet mask of a PLC's WiFi port, you can load the new subnet mask settings into the variables DM[100] to DM[103]  (e.g. from a HMI panel) and then invoke a function that runs SET_WIFI_SUBNET 100 to write the new subnet mask settings into the PLC.

• For Nano-10 and FMD PLCs,  you should backup the new subnet mask in FLASH (using the SETSYSTEM 252,0 command) and restart (cold boot) the PLC after changing the subnet mask settings so that the new subnet mask will be saved into the virtual EEPROM. This is not required for Fx and Wx PLCs.

• The PLC will only assume the new subnet mask after it has been rebooted (via the RESTART command or power-on reset).
This is applicable to all models.

• This command is ignored by i-TRiLOGI  simulator.
