12 Where to Start
The FlexLogix controller, part of the Logix family of controllers,
provides a small, powerful, cost-effective system built on the
following components:
• 1794-L34 FlexLogix controller available in 512 Kbytes of
user memory.
• FlexLogix controller that supports the Logix instructions.
• RSLogix 5000 programming software that supports every
Logix controller.
• FLEX I/O modules that provide a compact, DIN-rail mounted
I/O system.
• 1788 communication daughtercard that provides communication
over standard-based ControlNet, DeviceNet or EtherNet/IP
networks. The controller allows the insertion of daughtercards
for up to 2 networks (e.g., one for DeviceNet and one for
EtherNet/IP).
Design When designing a FlexLogix system, determine the network
configuration and the placement of components in each location.
Make these decisions as you design your system:
