DeviceNet Information

The device operates as a slave on the DeviceNet network. The unit
supports Explicit, Polled, Change-of-State and Cyclic I/O Messages of
the predefined master/slave connection set. It does not support the
Explicit Unconnected Message Manager (UCMM).

DeviceNet Message Types

As a group 2 slave device, the module supports the following
message types.

CAN IDENTIFIER GROUP 2 Message Type

10yyyyyy000 Master I/O Strobe Command Message

10xxxxxx010 Master Change-of-State/Cyclic Acknowledge Message

10xxxxxx100 Master Explicit Request Message

10xxxxxx101 Master I/O Poll Command Message

10xxxxxx110 Unconnected Explicit Request Message

10xxxxxx111 Duplicate MACID Check Message

xxxxxx = Node Address
yyyyyy = Master Address
