To return the SLC to factory settings, which includes a reset of the IP:

Remove power from the SLC 500 power supply.
Remove the processor from the chassis.
Disconnect the battery by removing the battery connector from its socket.
Locate the green resistor beside the battery. On the opposite side of the circuit board from the green resistor, locate the nearby VBB and GND connections.
Place a small bladed screwdriver across the VBB and GND connections and hold for 60 seconds. This returns the processor to the initial factory conditions.

For a graphical image of this process, see the second figure on pg. 25 of the SLC 500 Series manual.

Another option is to go online with the processor either through the existing IP address or through the serial port. Once online, go to: Channel Configuration > Chan. 1 System and then change the IP setting or select the Bootp Enable check box...

You may need to put the processor into program mode to accept the changes though - I can't specifically remember though.

By using this method (instead of the method described above), you don't have to worry about erasing the entire program.
