*1 Node addresses are distributed because the area occupied by a 32-point Output Unit, which occupies more
than one node address, is not overlapping with the area occupied by an 8-point Input Slave.
3-2-3 Allocation to Special I/O Unit Allocation Relay Area
(Communications Mode No. 0 to 3)
Allocation to the Special I/O Unit allocation relay area can be performed without CX-Integrator.
Follow the steps below.
1
Power on the inverter(s) first and configure the following settings according to 3-1
Inverter Configuration on page 3-2.
• Set the node address. According to Setting Slave Node Addresses on page 3-15, set the
rotary switches or CompoNet node address (P190).
• Set the type of Remote I/O. Set inverter parameter P046 (Assembly Instance No.) that suits
your application.
Precautions for Correct Use Precautions for Correct Use
• Be sure to set the type of Remote I/O at this point. No. of occupied words by the CompoNet
Communications Unit varies with the Remote I/O type. Unless the Remote I/O type is set
correctly, automatic network configuration cannot be completed successfully.
• To connect additional CompoNet Slaves, set the node addresses for them simultaneously
at this point.
2
Set the Special I/O Unit number (Machine No.) and communications mode number (MODE)
rotary switches on the Master Unit. Cycle the power supply of the inverter. Then, power on
all network components (Master Unit, other Slaves, communications power supply, etc.).
3
Once the inverter(s) and all network components are powered on, check that the Com-
poNet Communications Unit's LED indicators indicate normal operation.
If everything is correctly configured, both the MS (Module Status) LED and the NS (Network Sta-
tus) LED are lit green.
If the LED indicators indicate a different pattern, please refer to Section 6 Troubleshooting on
page 6-1 to take corrective action.
