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
