10.3 Component Descriptions
10.3.1 Controller
The ControlLogix controller, running RSLogix 5000 software, provides primary control.
Project-specific programs are created in a Windows-based system and uploaded to the
controller. The RSLogix 5000 software supports ladder and function block programming
and complies with the International Electrical Code (IEC) 61131-3 standard for
programmable controllers.
10.3.2 ControlNet 1.5
Operating at 5 Mbps, the network is repeatable and deterministic. Cabling is redundant
with two separate channels carrying the same information. The maximum total length of
the network is 1000 meters without the use of repeaters. However, this length decreases
based on the number of nodes on the network. A practical design limit is 800 meters.
10.3.3 Input/Output Modules
Flex I/O modules provide an interface between the package instrumentation and the
processor. Specific modules handle discrete inputs, analog inputs, temperature inputs,
speed inputs, discrete outputs and analog outputs.
