Allocating I/O from the Configurator Section 4-3
When a CS/CJ-series DeviceNet Unit is used, the IN Area can be divided into
two separate blocks by using two connection methods. This function is used
to allocate IN data in different areas.
Note The maximum allocation size for the IN and OUT Areas (100 words) applies to
the DeviceNet Communications Unit, and does not apply to the size of alloca-
tions in the Master Unit. For details on allocation sizes in the Master Unit, refer
to the operation manual for the Master Unit being used.
Creating Data from the DeviceNet Configurator (Ver. 2.44 or Higher) (or CX-Integrator
Ver. 2.2 or higher)
If problems occur in the connection with the Configurator, change the master
settings. Problems will occur if the master's message timeout time is too short
or the I/O size allocated in the master is different from that allocated in the
DeviceNet Communications Unit. For details on setting methods, refer to
