CJ-series Controller Link Units Section 4-2
4-2-2 Unit Number
Set the unit number for each Unit using the rotary switches on the front of the
Unit. The unit number is used to identify a CPU Bus Unit within the PC. Any
unit number can be set between 0 and F in hexadecimal (00 to 15 in decimal)
.
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
Note 1. Always turn OFF the PC’s power before setting the unit number.
2. When setting a Unit for the first time or changing the existing setting, create
a I/O table in the PC’s CPU Unit.
3. Do not set the same unit number twice within the same PC. An error will
occur if the same unit number is set for two different Unit, and the CPU Unit
will not be able to recognize the Units.
4. When the Unit is recognized by the PC’s CPU Unit, “NS” will be shown in
the I/O table displayed for the CX-Programmer programming device.
5. The default setting is “0.”
6. The unit number determines the words used by the Controller Link Unit in
PC memory.
4-2-3 Node Addresses
Set the node addresses of each Unit on the Network using the rotary switches
on the front of the Unit. The node address is used to identify each node in the
Network can be set to any number between 01 and 32.
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
Note 1. Always turn OFF the PC’s power before setting the node address.
2. Do not set the same node address twice within the same Network. An error
will occur if the same address is set for two different nodes. The ERC indi-
cator on the front of the Unit will light (Communications Error Flag) and ei-
ther communications will stop, or the INS indicator will not light and you will
be unable to participate in the Network.
3. The send sequence for the data link areas is determined according to the
sequence of node addresses for automatically set data links.
