DeviceNet is a cost effective solution to one kind application of control
c\area network. It reduces the connection wires between devices and provides
rapid troubleshooting rejection function. The transfer rate can be up to
500Kbps within 100 meters. The transfer distance can be up to 500 meters in
125Kbps (See Table 1.1). It allows direct peer to peer data exchange between
nodes in an organized and, if necessary, deterministic manner. Master/Slave
connection model can be supported in the same network. Therefore,
DeviceNet is able to facilitate all application communications based on a
redefine a connection scheme. However, DeviceNet connection object strands
as the communication path between multiple endpoints, which are application
objects that is needed to share data.

PISO-DNM100 can represent an economic solution of DeviceNet
application and be a DeviceNet master device on the DeviceNet network.
PISO-DNM100 supports Group 2 only Server and UCMM functions to
communication with slave devices. It has an independent CAN bus
communication port with the ability to cover a wide range of DeviceNet
applications. Besides, PISO-DNM100 uses the new CAN controller Phillips
SJA1000T and transceiver 82C250/251, which provide bus arbitration, error
detection with auto correction and re-transmission function. It can be installed
on almost any windows-based system, for example
Win98/Win2000/WinXP/WinNT. It is popularly applied in the industrial
automation, building automation, vehicle, marine, and embedded control
network. Therefore, that is an easy way to develop the DeviceNet network with
PISO-DNM100.
