DeviceNet Network
The DeviceNet network is an open low-level network that provides connections
between simple industrial devices (such as sensors and actuators) and higher-level
devices (such as PLCs and computers). The DeviceNet network uses the proven
Common Industrial Protocol (CIP) to provide the control, configure, and data
collection capabilities for industrial devices. The DeviceNet network is a flexible
network that works with devices from multiple vendors.
The following illustration shows the FLEX I/O platform on a DeviceNet
network.
