Object model In DeviceNet, data are accessed via objects. Each DeviceNet
station has one or more objects of various classes. An object
is an instance o
f a class:
 Standard classes describe e.g. basic features, the
communication behaviour or parameters of individual
channels of a slave.
 Manufacturer−specific classes desc
ribe device−specific
properties or parameters.
Device profile Device profiles define the minimum available objects and
communication functions for the specific de
vice types. The
SFC−LACI corresponds to the DeviceNet specification of the
device profile Communication Adapter" (device type number
000Ch).
Predefined connectionF
or simple slave devices, predefined master/slave
connections (Predefined Master/Slave Connection Sets")
can be used; these simplify the transmission of
tI/O data
between the higher−order controller (master) and the
decentralised peripheral devices (slaves). The SFC−LACI−DN
works according to the specification
Predefined connection
set, Group 2 slave only".
