DeviceNet® Master/Slave Module

DeviceNet® is a multi-drop network that connects programmable controllers and I/O devices, and is based on CAN (Controller Area Network) for its data link layer.

Connection to DeviceNet® compatible devices

The module can be implemented into DeviceNet® compatible devices as a DeviceNet® network and operate as either a master or slave station. Automatic configuration functionality enables the master station to detect slave stations on the network, thereby automatically creating the parameters.
