FlexLogix Controller System
Catalog number: 1794-L33, 1794-L34 & 1794-FLA
Before You Begin
Use this document as a guide for installing and powering-up your FlexLogix
controller system. This guide provides installation instructions for both the
FlexLogix controller (1794-L33, -L34) and the FlexLogix extended-local I/O adapter
(1794-FLA). You should already be familiar with the FlexLogix system components.
See the documentation references for additional information.
You must FLASH upgrade the firmware on your FlexLogix controller before you
can use it. The controller ships with firmware revision 1.x but must be upgraded to
match the version of RSLogix 5000 that you are using (e.g. if you are using
RSLogix 5000 V11, you must upgrade your FlexLogix controller firmware to revision
11.x before using it. For more information on upgrading your controller's firmware,
see page 19.
Tools That You Need
· slotted screwdriver
· phillips screwdriver
· mounting hardware (for mounting a DIN rail)
· drill (for mounting a DIN rail)
· needle-nose pliers
IMPORTANT
Installation instructions ship with each FlexLogix component. If
you want the FlexLogix System User Manual, publication
1794-UM001, you can obtain it as follows:
· download an electronic version or place an order over the
