Communication Connections Chapter 5
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), or other controllers
that support CIP Serial over DF1 Full-Duplex, such as ControlLogix and
CompactLogix controllers that have embedded serial ports.
EtherNet/IP, supported on the Micro850 controller, makes use of the standard
Ethernet TCP/IP protocol. The Micro850 controller supports up to 16
simultaneous EtherNet/IP Server connections.
To configure CIP Serial, see
Configure CIP Serial Driver on page 47
To configure for EtherNet/IP, see
Configure Ethernet Settings on page 52
CIP Symbolic Addressing
Users may access any global variables through CIP Symbolic addressing except for
system and reserved variables.
One- or two-dimension arrays for simple data types are supported (for example,
ARRAY OF INT[1..10, 1..10]) are supported but arrays of arrays (for example,
ARRAY OF ARRAY) are not supported. Array of strings are also supported.
Supported Data Types in CIP Symbolic
Data Type
