The set values of the Local IP Address Switches (rotary switches 1 to 8) on the
back of the Ethernet Unit are read and stored here when the power is turned ON.
If an incorrect address is set, 0000 (Hex) will be stored here and the ERC indica-
tor will flash. (Refer to 3-4-3 Setting the Local IP Address.)
