3) The node address is set between 1 and 64. The following table shows setting the node
address.
Table 4.25 Setting the Node Address
Example
Setting of Node Address 2
Node Address Rotary Switch 1 Rotary Switch 2
Rotary Switch 1 1 to 9 0 1 to 9
10 to 19 1 0 to 9
20 to 29 2 0 to 9
30 to 39 3 0 to 9
40 to 49 4 0 to 9
50 to 59 5 0 to 9
Rotary Switch 2
60 to 64 6 0 to 4
Note (1) The setting of the rotary switches is effective (read) only when power is turned ON to
the Power Supply Module of the CPU Rack.
(2) Set the node address to between 1 and 64. If the address is set to 0 or, to 65 or above,
normal communications will not be possible.
(3) The same node address must not be used more than once within a single network. If
communications devices in the same network have the same node address, correct
communications will not be possible.
7. Built-in Battery
1) The CPU Module is equipped with one replaceable battery. This battery provides backup
for programs or data stored in the CPU Module and 4-axis Motion Module. The battery
backup prevents the program and data from being lost when the power supply to the
Power Supply Module in the CPU Rack is turned off.
When the Motion Module controls a servomotor with a built-in absolute encoder, use a
JRMSP-120XCP96000 Battery Module as a power supply for the encoder’s backup cir-
cuit. The CPU Module’s built-in battery cannot be used as a power supply for the absolute
encoder’s backup circuit.
2) The built-in battery has enough power to back up the contents of memory through a total
of one year of power interruptions. The battery itself has a guaranteed lifetime of 5 years,
although this lifetime varies with the ambient temperature and usage conditions.
3) When the CPU Module’s “BAT ALM” LED lights, be sure to replace the battery with a
BR-2/3A-1 replacement battery within two weeks. The program and data stored in the
CPU Module or 4-axis Motion Module will be lost if the battery isn’t replaced within two
weeks.
