Summary of M340 CPU rotary switch for Valid IP Address Settings:
Each rotary switch position that you can use to set a valid IP address is marked on the module
The following information summarizes the valid address settings:
  • Device name: For a switch-set device name, select a numeric value from 00 to 159. You can use both switches
  • On the upper switch (Tens digit), the available settings are 0 to 15
  • On the lower switch (Ones digit), the available settings are 0 to 9
  • The selection on the lower switch of any non-numeric (BOOTP, STORED, CLEAR IP,DISABLED) makes the setting on the upper switch inconsequential
  • BOOTP: To get an IP address from a BOOTP server, select either of the two BOOTP positions on the bottom switch
  • STORED: The device uses the application’s configured (stored) parameters
  • CLEAR IP: The device uses the default IP parameters
  • DISABLED: The device does not respond to communications
