SynchLink Transmitted Axes
Before SynchLink became available, all coordinated motion axes had
to be controlled from the same ControlLogix chassis. However,
SynchLink allows you to coordinate axes between multiple chassis.
The 1756-SYNCH module can consume up to two axes from a master
chassis and broadcast the data to other chassis over SynchLink.
Slave chassis consume the broadcast axis data and redistribute it to
their local motion planners (i.e. the Logix controller in their local
chassis). The controller in the slave chassis must be configured to
consume axis data from the local 1756-SYNCH module. With this
configuration, you can control multiple axes synchronously
throughout the system.
SynchLink is typically used by the 1756-SYNCH module for axis data
and CST synchronization. The 1756-DMxxx series modules and the
PowerFlex 700S products typically use SynchLink to pass drive data
(via direct data or buffered data).
In this chapter you read about:
· what SynchLink is.
· what SynchLink is used for.
Chapter 2 explains the SynchLink Topologies.
