This term: Has the following definition:
Links
A link is a software connection between a linkable sink parameter and a
source parameter. You can use links to transfer data from the source
parameter to a linkable sink parameter. Your 1336 FORCE user manual
provides a list of linkable sink parameters.
The PLC Communications Adapter Board allows up to 50 links in
addition to 4 analog output links. You can only program links when the
drive is not running. Links are stored in BRAM and established at power
up, BRAM recall, and/or system reset.
There are two types of links:
• User Link –– A user link is a software connection that you establish.
You can change these links as needed.
• Default Link –– A default link is a software connection between two
parameters that is made when the drive is initialized.
The default links are shown here. The links are made from the source
side, and the data transfer occurs in the opposite direction.

Mask
parameters
Through the SCANport interface, up to five different SCANport adapters
and two different remote I/O (RIO) devices can control the 1336 FORCE.
With this flexibility, conflicts are inherent. The PLC Communications
Adapter Board allows you to make functional masks. At each port, you
can selectively lock out functions such as start, jog, and drive direction as
well as many fault interlocks by using mask parameters to select the
allowable functions for each port.
Non–volatile
memory
Non–volatile memory is data memory in the drive that retains the values
of all data even when power is disconnected from the drive. BRAM
(Battery backed Random Access Memory) chips are used for the
non–volatile memory to store some of the drive parameters, links, and
user text.
