SET_WIFI_DNS  dmindex
Purpose To set the DNS address of this PLC's WiFi port using the parameters stored in DM[dmindex] to DM[dmindex+3].
Examples 
	
	DM[100] = 192
	DM[101] = 168
	DM[102] = 0
	DM[103] = 1
	SET_WIFI_DNS 100	' Set the DNS address to 192.168.0.1
	SETSYSTEM 252,0 	' (only required for Nano-10 and FMD PLCs)    
	RESTART 		' Reboot the PLC
Comments:

  • To change the DNS address of a PLC's WiFi port, you can load the new DNS address into the variables DM[100] to DM[103]  (e.g. from a HMI panel) and then invoke a function that runs SET_WIFI_DNS 100 to write the new DNS address into the PLC.
  • For Nano-10 and FMD PLCs,  you should backup the new DNS in FLASH (using the SETSYSTEM 252,0 command) and restart (cold boot) the PLC after changing the DNS address so that the new DNS address will be saved into the virtual EEPROM. This is not required for Fx and Wx PLCs.
  • The PLC will only assume the new DNS address 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.
