SYSTEM DESCRIPTION
The POWER WAVE 405 and Power Feed family of
products utilize a digital communication system called
Linc-Net. Simply put, Linc-Net allows large amounts of
information to be passed at very high speeds between
components (nodes) in the system. The system
requires only two wires for communication, and
because of its bus-like structure, the components may
be connected to the network in any order, thus simpli-
fying the system set-up.
Each "system" must contain only one power source.
The power source may be connected to a maximum
of four feeder groups. Each group containing one user
interface (UI), and up to seven Feed Heads (FH). SEE
FIGURE A.1. The UI controls all of the FH
’ s of that
group. The UI ’ s and FH ’ s are assigned to groups by
setting a code on the DIP switches mounted on their
individual control boards. For example all of the FH
’ s
to be controlled by a given UI must have their "Group
ID" switches set to the same group number as the UI.
In addition, each FH must be assigned a separate FH
number within that group. See the system set-up sec-
tion for further details.
From a network perspective, each component in the
system is considered a separate node, regardless of
its physical location. For example, even though a UI
and FH may be physically mounted together, they are
still viewed as separate pieces (nodes) by the net-
work, and can only communicate via Linc-Net. The
Linc-Net connection is generally made external
through the Linc-Net Control Cable, but can also be
made internally, as with the PF-10 bench model feed-
er.
The most common Linc-Net configuration (called a
simple system) consists of one power source, one
user interface and one feeder. Under these circum-
stances the group and feed head ID DIP switches are
ignored and the system will function regardless of
their position. The same is true for the minimum sys-
tem consisting of a power source and one UI
(Example: a stick welding system).
