Configuring DataLinks DataLinks are supported in the SMC Flex. A DataLink is a mechanism used by
most drives to transfer data to and from the controller without using an Explicit
Message. The SMC Flex supports 16bit DataLinks, therefore the device can be
configured to return up to four additional pieces of information without the
need for an explicit message.
Rules for Using DataLinks
• Each set of DataLink parameters in an SMC Flex can be used by only one
adapter. If more than one adapter is connected, multiple adapters must not
try to use the same DataLink.
• Parameter settings in the SMC determine the data passed through the
DataLink mechanism.
• When you use a DataLink to change a value, the value is not written to the
Non-Volatile Storage (NVS). The value is stored in volatile memory and
lost when the drive loses power.
Parameters 88…103 are used to configure the DataLinks. For additional
information regarding DataLinks, refer to the user manual for the
communication interface being used.
Note: Node addressing of the DPI communication card can be programmed via
software or a hand-held DPI HIM. The on-board HIM cannot be used to
address the communication card.
Updating Firmware The latest version of firmware and instructions for the SMC Flex can be obtained
from www.ab.com.
Note: The MV SMC Flex must use firmware release 6.003 or later. This User
Manual pertains to units with firmware release 6.003 or later.
