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 16-bit 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 to 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 3.006 or later.
