Drive Module/PowerFlex 700s Drives Combination
In this configuration, a SynchLink module acts as a time relay and
synchronizes the CST with the beacon to communicate data to the
Drive modules and the PowerFlex 700s drives. The Drive modules use
the CST to synchronize their VPLs, and the PowerFlex 700S drives use
the SynchLink node clock to synchronize their VPLs.

Restrictions
Typical applications
(1)
The local Logix controller must move the axis or buffered data for a 1756-SYNCH module. For the 1756-DMxxx
module or PowerFlex 700S drives, the device's VPL microprocessor must move the data. For more information,
see page 1-7.

Explanation:
Master - 1756-SYNCH
Slave - 1756-DMxxx series modules and PowerFlex 700S
drives.
The 1756-SYNCH module synchronizes the CST and SynchLink
node clocks.
· Typically, this configuration is used to transfer direct data.
· If you want to pass buffered data, the local controller at
each node must pass the data.
Axis data is not supported in the configuration.
