17. Communication
• Commonly used communication protocol are
DH+
DH485
Device Net
Control Net (MCL)
Ethernet (MCL)

18. • Data Highway-proprietary data network used by AB
to communicate information to & from PLC’s on the
network or to & from host computers attached to
the network
• Device Net- Low cost communication link connects
industrial devices to a Network. It is based on Broad
cast-oriented communication protocol (Controller
Area Network-CAN)
• Control Net- Real time control-layer NW providing
High speed transport of both time-Critical I0 Data &
messaging data including upload/download of
programming & configuration data, peer-peer
messaging on a single physical media link

19. • Ethernet- Standard for Local communications Nw
developed jointly by Digital Equipment, Xerox &
Intel.
• Ethernet baseband coaxial cable transmits data at
speeds up to 100 Mbps is used as the underlying
transport vehicle by several upper level protocols
including TCP/IP.

20. How protocols is distinguished
• Number of Nodes supported
• Total network Length
• Speed of communication
