CsCAN has advantages that DeviceNet does not have. CsCAN and DeviceNet are similar networks. Both networks are based on the CAN specification developed by Bosch. CsCAN follows the basic DeviceNet configuration for wiring. Both networks use the “trunk and tap” wiring configuration. With CsCAN, the maximum distance the network can be is 1500 meters (with repeaters). With DeviceNet, the maximum distance you can have is 500 meters. With CsCAN, you can have up to 253 nodes on the network (using 3 repeaters). With DeviceNet, the maximum number of nodes on the network is 64. The network speed for CsCAN is from 125Kbaud to 1Mbaud. For DeviceNet, it is 125Kbaud to 500kbaud. CsCAN is a peer to peer network (no master device is needed). DeviceNet is a master-slave network and requires a master device. Each OCS node would be a slave. CsCAN uses global data and DeviceNet does not. With CsCAN, you are able to program/monitor/trouble-shoot controllers over the network. You can not do this with Device
