Setting the Front Panel Switches
Setting Unit Numbers
Always set the unit numbers so that the unit numbers of other CPU Bus Units mounted to the
same CPU Unit are all unique.
Use a small screwdriver to set the rotary switches, being careful not to damage them.
The factory setting is 0.
Setting Node Numbers
Set the node numbers as hexadecimal values with the node number setting switch. Always
set the node numbers so that other Ethernet Units connected to the same Ethernet network
all have unique addresses. As long as the addresses are unique, they can be set between 01
and 7E (1 to 126 decimal).
Set the upper digit using the top rotary switch and the lower digit using the bottom rotary
switch.
The factory setting is 01.
When using automatic generation to convert addresses, set the node number to the same
value as that of the rightmost byte of the local IP address. If the same values cannot be set,
the IP address table method or combination method must be used to convert the addresses.
