Modbus TCP Client/Server

The Modbus TCP Client/Server communication protocol uses the same
Modbus mapping features as Modbus RTU, but instead of the Serial port, it is
supported over Ethernet. Modbus TCP Server takes on Modbus Slave features on
Ethernet.
No protocol configuration is required other than configuring the Modbus
mapping table. For information on Modbus mapping, see
Micro800 on page 241.
Use MSG_MODBUS2 instruction to send Modbus TCP message over
TIP
Ethernet port.
With Connected Components Workbench software version 12 or later, the
Modbus TCP Server is disabled by default. If you want to use Modbus TCP, you
can enable it from the Ethernet settings.

CIP Symbolic Client/Server

CIP Symbolic is supported by any CIP compliant interface including Ethernet
(EtherNet/IP) and Serial Port (CIP Serial). This protocol allows HMIs to easily
connect to the Micro830/Micro850/Micro870 controller.
Micro850 and Micro870 controllers support up to 16 simultaneous EtherNet/IP
Client connections and 23 simultaneous EtherNet/IP Server connections.
CIP Serial, supported on Micro830, Micro850, and Micro870 controllers, makes
use of DF1 Full Duplex protocol, which provides point-to-point connection
between two devices.
The Micro800 controllers support the protocol through RS-232 connection to
external devices, such as computers running RSLinx® Classic software, PanelView
Component terminals (firmware revisions 1.70 and above), PanelView 800
terminals or other controllers that support CIP Serial over DF1 Full-Duplex,
such as ControlLogix® and CompactLogix™ controllers that have embedded serial
ports.
