The DEP-100S communicates with each device through MedLAN
(WTC’s Local Area Network). This proprietary communications
protocol defines the formatting of messages and commands. This
scheme allows WTC’s computer-based devices to share
information by allowing one DEP-100S to communicate with up
to 30 weld controls.
MedLAN designates the DEP-100S as the “master” device
(controlling all data transmissions). The weld control units are
considered the “slave” devices, because they cannot initiate
communications. (They can only respond to requests for data
from the DEP-100S.)

The DEP-100S sends each transmission to a specific device, which
is identified as a unique location on the network, identified by an
address.
Each weld control responds only to the messages sent to its
address. The address of each control is determined by its
MedLAN base address.
To program the MedLAN address for a weld control you’ll use
the Network Addressing features provided in the Program Mode
display. (For more information, see “Network Address” on page
2-18.)
Note:
In some weld devices, the MedLAN address is determined
by the weld control hardware. Refer to the Operator’s
Manual provided with your weld device.

You’ll see this message in the upper
right to indicate data is being transmit-
ted between the DEP-100S and a weld
control.
