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
