10 Select FLEX I/O Communication Adapters
DLR network using EtherNet/IP taps. The following is an illustration of how
FLEX I/O systems can be integrated into a DLR topology.
ControlNet Network
ControlNet is a real-time control network that provides high-speed transport of
both time-critical I/O and interlocking data and messaging data, including
upload/download of programming and configuration data on a single physical
media link. The ControlNet network’s highly efficient data transfer capability
significantly enhances I/O performance and peer-to-peer communication in any
system or application where it is used.
The 1794-ACNR15 adapter is capable of accepting redundant ControlNet cable
media. The 1794-ACN15 is a non-redundant version.
The following diagram shows the FLEX I/O platform on a ControlNet network.
