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.
ASCII
ASCII provides connection to other ASCII devices, such as bar code readers,
weigh scales, serial printers, and other intelligent devices. You can use ASCII by
configuring the embedded or any plug-in serial RS232 or RS485 port for the
ASCII driver. Refer to the Connected Components Workbench Online Help for
more information.
To configure the serial port for ASCII, see Configure ASCII
on page 57.
CIP Communications
Pass-thru
The Micro820 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. The maximum number of supported hops is one. 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.

REMLCD
The user can download a program from the PC to controller1 through the
USB to serial port conversion via the Remote LCD. Also, the program can
be downloaded to controller2 and controller3 over USB to EtherNet/IP but
the performance is limited by the serial connection.
