Chapter 5 Communication Connections
CIP Client Messaging
CIP Generic and CIP Symbolic messages are supported on Micro800 controllers
through the Ethernet and serial ports. These client messaging features are enabled
by the MSG_CIPSYMBOLIC and MSG_CIPGENERIC function blocks.
See Micro800 Programmable Controllers: Getting Started with CIP Client
Messaging, publication 2080-QS002
, for more information and sample
quickstart projects to help you use the CIP Client Messaging feature.
Sockets Client/Server TCP/UDP
Sockets protocol is used for Ethernet communications to devices which do not
support Modbus TCP and Ethernet/IP. Sockets support client and server, and
TCP and UDP. Typical applications include communicating to printers, barcode
readers, and PCs.
CIP Communications
Pass-thru
The Micro830, Micro850, and Micro870 controllers support pass-thru on any
communications port that supports Common Industrial Protocol (CIP) for
applications such as program download. It does not support applications that
require dedicated connections such as HMI. Micro830, Micro850, and
Micro870 controllers support a maximum of one hop. A hop is defined to be an
intermediate connection or communications link between two devices – in
Micro800, this is through EtherNet/IP or CIP Serial or CIP USB.
Examples of Supported Architectures
USB to EtherNet/IP

EtherNet/IP
The user can download a program from the PC to controller1 over USB.
Also, the program can be downloaded to controller2 and controller3 over
USB to EtherNet/IP.
