You can use these node interfaces on a Data Highway II link:
Asynchronous Foreign-Device/DHII Interface (Cat. No. 1779-KFL)
Redundant Asynchronous Foreign-Device/DHII Interface
(Cat. No. 1779-KFLR)
Synchronous Foreign-Device/DHII Interface (Cat. No. 1779-KFM)
Redundant Synchronous Foreign-Device/DHII Interface
(Cat. No. 1779-KFMR)
PLC-2/DHII Interface (Cat. No. 1779-KP2)
Redundant PLC-2/DHII Interface (Cat. No. 1779-KP2R)

The Data Highway II network is a local area network (LAN) for the
industrial environment that provides peer-to-peer communication between
nodes. A Data Highway II network is illustrated in Figure 2.5.
