3.2 Predefined Master Slave Connection Set
The CAN-8124/CAN-8224/CAN-8424 has a “Predefined Master Slave
Connection Set” device. Users must understand these connection sets to know
how to operate the device. The following section explains what the “Predefined
Master Slave Connection Set” is.
When using the Predefined Master Slave Connection Set, DeviceNet
allows devices with fewer resources to take part in DeviceNet network
communication. For this reason a set of identifiers has been reserved within
Message Group 2 to simplify the movement of I/O and configuration data
typically seen in Master/Slave relationships. The steps which are necessary to
create and configure a connection between devices has been removed within
the Predefined Set. The Predefined Master Slave Connection Set allows for
the establishing of a DeviceNet communication environment using less
network and Device resources. The Predefined Set contains one Explicit
Messaging Connection and allows for several different I/O connections which
include a Bit Strobe Command/Response, Poll Command/Response, Change
of State and Cyclic connections. The following types of messages are
processed by a DeviceNet Slave
