Preface P–5
Publication 1336 FORCE–5.18 –– March, 1999
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 ControlNet 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.

Mask parameters
Through the SCANport interface, up to five different SCANport
adapters can control the 1336 FORCE. With this flexibility, conflicts
are inherent. The ControlNet 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.
Owner
parameters
The ControlNet Adapter Board allows one or more control devices or
adapters to own start, jog, direction, and other control functions. To
avoid conflict, some owners are exclusive. For example, only one
device can issue a forward direction speed command. Others have
multiple control. For example, all devices can jog the drive in the
forward direction, but only at a set speed. Devices can, for example,
jog the drive in the forward direction only if the jog mask parameter
allows for it.
Parameter entry
A parameter entry refers to the information stored in the drive that
contains the parameter number, parameter data, and all other
information related to the specific parameter.
Parameter table
A parameter table is a table of parameter entries for all configuration
sink and source parameters in the drive.
