Communication Choices 5
1785-SO036C-EN-P - April 2002
The networking capabilities, lead by EtherNet/IP network,
ControlNet network, and DeviceNet network, allow information
exchange between a range of devices and computing platforms and
operating systems. PLC-5 controllers come with different network
connections. Choose the network(s) that best meets your needs:
Communication Choices
If your application requires: Use this network: Type:
• high-speed data transfer between information systems and/or a
large quantity of controllers
• Internet/Intranet connection
• program maintenance
EtherNet/IP network
see page 6
information network
• plantwide and cell-level data sharing with program maintenance
Data Highway Plus
TM
see page 11
information network
• high-speed transfer of time-critical data between controllers and
I/O devices
• deterministic and repeatable data delivery
• program maintenance
• media redundancy or intrinsic safety options
ControlNet network
see page 7
control and information
network
• connections between controllers and I/O adapters
• distributed controllers so that each controller has its own I/O and
communicates with a supervisory controller
Universal Remote I/O
see page 12
control network
• connections of low-level devices directly to plant floor controllers,
without the need to interface them through I/O modules
• more diagnostics for improved data collection and fault detection
• less wiring and reduced start-up time than a traditional,
hard-wired system
DeviceNet network
see page 8
device network
• modems
• messages that send and receive ASCII characters to or from devices
such as ASCII terminals, bar code readers, message displays, weigh
scales, or printers
• supervisory control and data acquisition (SCADA)
