Before You Begin Consider the following when planning your CompactLogix system:
•The CompactLogix controller is always the leftmost module in the
system.
•The controller must be within four modules of the system power
supply. Some I/O modules may be up to eight modules away from the
power supply. See the documentation for your 1769 I/O modules for
details.
•The 1769-L32E controller supports as many as 16 I/O modules and the
1769-L35E controller supports as many as 30 I/O modules. Both
controllers can use a maximum of 3 I/O banks with 2 expansion cables.
•Each I/O bank requires its own power supply.
•Only one controller can be used in a CompactLogix system.
•A 1769-ECR right end cap or 1769-ECL left end cap is required to
terminate the end of the communication bus.
Parts List
These components are shipped with the controller.
You may also use these components with the controller.
Set the Node Address
(ControlNet only)
Every ControlNet network requires at least one module that can store parameters
and configure the network with those parameters upon startup. The
CompactLogix controller is called a keeper because it keeps the network
configuration.
The CompactLogix controller can keep the network parameters at any legal node
address (01…99). Multiple devices on any one network can act as the network
keepers. Each device capable of being the network keeper acts to back up the
current keeper. This back-up function is automatic and requires no action on
your part.
