SYSTEM DESCRIPTION

The POWER WAVE 355/405 and Power Feed 10/11
family of products utilize a digital communication sys-
tem 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
simplifying 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.
System Model
INSTALLATION
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 network,
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 internal-
ly, as with the PF-10 bench model feeder.
The most common Linc-Net configuration (called a
simple system) consists of one power source, one user
interface and one feeder. Under these circumstances
the group and feed head ID DIP switches are ignored
and the system will function regardless of their posi-
tion. The same is true for the minimum system con-
sisting of a power source and one UI (Example: a stick
welding system).
