For the fixed allocations, the configuration can be done without the DeviceNet
configurator. The output and input data of the slaves are allocated strictly in
order of node address in the areas. The Master Unit will check the Default
connection path of the actual Slave to select which assemblies will be used for
the configuration.
The following steps are based on configuration of the OMRON CJ1W-DRM21
Master Unit using CX-Integrator tool.
Connect CX-Integrator to the network through a serial line or other interface.
Turn ON the communications, inverter(s), and Master Unit or PLC power sup-
plies.
Open the Configurator and perform the User-set allocation sequence as
defined for the Master Unit.
Create network topology by either
• offline operation adding Master Unit and Slaves or
• uploading connected network.
Be sure to match the project's Slave node numbers with the actual numbers of
the Unit's (as set with inverter parameter P192).
In the Master Unit's Edit Device Parameter window (General tab), register the
Device List for the connected Devices.
Use the Advanced setting for the Slave to select the connection and assem-
blies required. See note.
Go to the I/O allocation (IN/OUT) tabs to allocate the IO assemblies of the
Slaves to PLC memory.
Save and download the configuration to your DeviceNet Master Unit.
Once the network is re-started with the new settings, check that the Option
Board LED indicators indicate proper operation: If everything is correctly con-
figured, both the MS (Module Status) LED and the NS (Network Status) LED
will be Green. Please refer to section 5-1 Troubleshooting Using the LED Indi-
cators for troubleshooting any configuration errors if the LED indicators are
displaying a different pattern.
