PISO-DNM100 DeviceNet Master API functions User’s Manual (Ver: 1.0) 2008/02/25 6DeviceNet is a cost effective solution to one kind application of controlc\area network. It reduces the connection wires between devices and providesrapid troubleshooting rejection function. The transfer rate can be up to500Kbps within 100 meters. The transfer distance can be up to 500 meters in125Kbps (See Table 1.1). It allows direct peer to peer data exchange betweennodes in an organized and, if necessary, deterministic manner. Master/Slaveconnection model can be supported in the same network. Therefore,DeviceNet is able to facilitate all application communications based on aredefine a connection scheme. However, DeviceNet connection object strandsas the communication path between multiple endpoints, which are applicationobjects that is needed to share data.Baud rate (bit/s) Max.

It has an independent CAN buscommunication port with the ability to cover a wide range of DeviceNetapplications. Besides, PISO-DNM100 uses the new CAN controller PhillipsSJA1000T and transceiver 82C250/251, which provide bus arbitration, errordetection with auto correction and re-transmission function. It can be installedon almost any windows-based system, for exampleWin98/Win2000/WinXP/WinNT. It is popularly applied in the industrialautomation, building automation, vehicle, marine, and embedded controlnetwork. Therefore, that is an easy way to develop the DeviceNet network withPISO-DNM100.
