Communicate over Networks
All CompactLogix™ 5370 controllers support these tasks over an
EtherNet/IP
network
:
•
Control distributed I/O
•
Send/receive messages to/from other devices on the same network or
another network
•
Produce/consume (interlock) data between controllers
•
Socket interface
CompactLogix 5370 L2 and L3 controllers support these tasks over a
DeviceNet
network
:
•
Control distributed I/O
•
Send messages to devices on the same network; the controller cannot
receive messages from other devices on the network.
All CompactLogix 5370 controllers also support temporary connections from
your computer via a USB connection.
EtherNet/IP Network
Communication
The EtherNet/IP network offers a full suite of control, configuration, and data
collection services by layering the Common Industrial Protocol (CIP) over the
standard internet protocols, such as TCP/IP and UDP. This combination of
well-accepted standards provides the capability that is required to support
information data exchange and control applications.
The CompactLogix 5370 controllers use socket interface transactions and
conventional communication over the EtherNet/IP network to communicate
with Ethernet devices that do not support the EtherNet/IP application protocol.
For more information on socket interface transactions, see
CompactLogix 5370 Controllers on page 133
