Note	Refer to 6-3 Using FINS Message Communications for details on FINS com-
	munications.
User-set allocations	With CS/CJ-series DeviceNet Units, remote I/O communications can be allo-
without the Configurator	cated in any area without the Configurator simply by using DM Area settings.
	If the Configurator is used, it allows you to change the node address order for
	more flexible I/O allocations. This feature ensures the proper I/O allocations
	for any application and it makes effective use of PC memory by simplifying
	programming.
Note	Refer to 4-4 User-set Allocations for details.
Slave Functions	CS/CJ-series DeviceNet Units can be used as both masters and slaves, and
	master and slave communications can be executed either separately or simul-
