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:
