Communications Instructions 21-7
Local Messages
The controller is capable of communicating using local or remote
messages. With a local message, all devices are accessible without a
separate device acting as a bridge. Different types of electrical interfaces
may be required to connect to the network, but the network is still
classified as a local network. Remote messages use a remote network,
where devices are accessible only by passing or routing through a device
to another network. Remote networks are discussed on page 21-16.
Local Networks
The following three examples represent different types of local networks.
Example 1 - Local DH-485 Network with AIC+ (1761-NET-AIC) Interface
Example 2 - Local DeviceNet Network with DeviceNet Interface (1761-NET-DNI)
