3-2 Communicate with the Interface Module
Full-duplex (Point-to-point)
Full-duplex (Point-to-point)
This illustration shows a connection to a single remote SLC node. The
1747-C13 cable eliminates the need for a 1747-AIC link coupler for
connections to one node.
Full-duplex (Network Example)
Full-duplex (Network Example)
This illustration shows a connection to a remote DH-485 network of
up to 31 SLC nodes.
Half-duplex DF1 Protocol
The module provides two modes of half-duplex addressing: local and
remote. Local mode is provided for compatibility with earlier DF1
products, such as the Data Highway/Data Highway Plus
Asynchronous Interface Module (catalog number 1770-KF2) and when
only one interface module is used in the system.
