SET_GATEWAY  dmindex
Purpose To set the GATEWAY address of this PLC's built-in Ethernet port using the parameters stored in DM[dmindex] to DM[dmindex+3].
Examples DM[100] = 192
DM[101] = 168
DM[102] = 1
DM[103] = 1

SET_GATEWAY 100   ' set the GATEWAY address to 192.168.1.1

SETSYSTEM 252,0 ' required for Nano-10 and FMD PLCs

RESTART ' power cycle the PLC

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