B-2 Configuring the Star Configuration
Using Remote Axis Control Most applications using the ControlLogix SynchLink module use it for
Remote Axis Control. You can use the SynchLink module to produce axes
from a master chassis and broadcast the data to other chassis.
Slave chassis consume the broadcast axis data and redistribute it to their local
motion planners (i.e. the Logix controller in their local chassis). With this
configuration, you can control multiple axes synchronously throughout the
system.
Configure Time Master Chassis - Master Node
You must complete the following tasks to configure the time
master chassis.
• Create a New RSLogix 5000 Project
• Add a SynchLink Module
• Configure the SynchLink Module
– Name the module
– Choose a receive communications format
– Choose a transmit communications format
– Choose an electronic keying option
– Set the RPI
– Determine if the module is the CST Time Master for
the chassis
– Make the module the Time Master for the SynchLink
• Download Configuration
IMPORTANT
This example assumes you have already set-up axis data
tags for the data the controller in the Time Master chassis
produces; this manual does not intend to explain how to
plan the motion portion of your application as that is a
controller function.
If you do not know how to set-up remote axis data tags and
account for them in the motion portion of your
application, see the ControlLogix Motion Module Setup &
Configuration User Manual, publication 1756-6.5.16.
