SynchLink™ Board for PowerFlex® 700S Drives
with Phase II Control
What is SynchLink?
SynchLink is a fiber optic communication link that allows its users to
implement distributed motion and drive systems based on ControlLogix and
PowerFlex700S products.
SynchLink should be used in conjunction with a standard control network,
such as ControlNet or Ethernet/IP. A standard network is used for general
control interlocking and transfer of diagnostic data across the system.
SynchLink does not function as a standard control network (e.g. it only
broadcasts data).
The PowerFlex 700S Drives transfer two types of data between drives,
including:
•
Direct - Data delivered in a single message. A SynchLink message can
contain a maximum of four direct data words; each word is 32 bits in
length. Direct data can be automatically forwarded to the next
SynchLink node in the daisy chain or ring configurations.
•
Buffered - Data that exceeds the four word limit of a direct data transfer.
Buffered data is appropriately segmented at the transmitting device and
reassembled at the receiving device. Buffered data cannot be
automatically forwarded to the next SynchLink node in the daisy chain
and ring configurations.
Refer to the SynchLink Design Guide, publication 1756-TD008..., when
planning and connecting the SynchLink network.
Refer to SynchLink™ Board for PowerFlex® 700S Drives with Phase II
Control, publication 20D-IN010..., for information on installing the
SynchLink option board.
