Communication Connections
Overview
This chapter describes how to communicate with your control system and
configure communication settings. The method you use and cabling required to
connect your controller depends on what type of system you are employing. This
chapter also describes how the controller establishes communication with the
appropriate network. Topics include:
The Micro830, Micro850, and Micro870 controllers have the following
embedded communication channels:
• a non-isolated RS-232/RS-485 combo port
• a non-isolated USB programming port
In addition, the Micro850 and Micro870 controllers have an RJ-45 Ethernet
port.
Supported Communication
Protocols
Micro830, Micro850, and Micro870 controllers support communication
through the embedded RS-232/RS-485 serial port as well as any installed serial
port plug-in modules. In addition, Micro850 and Micro870 controllers also
support communication through the embedded Ethernet port, and can be
connected to a local area network for various devices providing 10 Mbps/100
Mbps transfer rate.
These are the communication protocols supported by
Micro830/Micro850/Micro870 controllers:
• Modbus RTU Master and Slave
• CIP Serial Client/Server (RS-232 only)
• CIP Symbolic Client/Server
• ASCII
These are the communication protocols supported by Micro850 and Micro870
controllers only:
