Allocating Data in the Master
Section 4-4
4-4-2
User-set Allocations
With user-set allocations, the Configurator can be used to allocate DeviceNet
Communications Unit data anywhere within the specified DeviceNet area.
Note
1.
When performing user-set allocations from a DeviceNet Configurator, use
Ver. 2.31 or later.
2.
When the IN Area is divided into two blocks, the total number of words that
can be used for allocating data in the IN Area is still 100 words.
3.
When using a CS/CJ-series DeviceNet Unit as the master, the location and
size of the DeviceNet Area can be specified through the allocated DM Area
words, without using the Configurator. For slaves, however, I/O is allocated
in the DeviceNet Area in node-address order. For details, refer to the
CS/CJ-series DeviceNet Unit Operation Manual (W380).

Double-click the icon of the Master Unit in the Network Configuration Win-
dow, or select Device, Parameters, and Edit to display the Edit Device Pa-
rameters Window for the master.
2.
Click the Register Device Button in the master’s General Tab Page, and
register the DeviceNet Communications Unit. Alternatively, in the Network
Configuration Window, drag and drop the DeviceNet Communications Unit
icon in the Master Unit icon to register it. Once registered, the DeviceNet
Communications Unit will be added to the Register Device List field. By
registering the DeviceNet Communications Unit, the allocation data creat-
ed in the slave’s Edit Device Parameters Window will be registered in the
master.
3.
Select the I/O Allocation (OUT) and I/O Allocation (IN) Tab, and check
that the allocation data created in the Edit Device Parameters Window for
the DeviceNet Communications Unit parameters is registered in the mas-
Register Device Button
