5. COMMUNICATION
The following menu screens tell you how to set the Control's communication and data options.
However, to enable the Control to perform these functions, you must install the software from the
optional
DC25/UB25/HF25 Datacom Communications Interface Kit , commonly referred to as "the
Datacom kit” or Weldstat in a host computer. The Datacom Operator Manual describes cables,
connections, RS-232 operation, RS-485 operation, sample weld reports, data collection, and how to use
remote commands. The Datacom Kit allows you to connect a single Control, or multiple Controls, to a
printer or a computer in order to:
•
Compile, store, view, and print weld history data for detailed analysis.
•
Remotely program weld schedules on the Control(s).
•
Remotely program menu items on the Control(s).
Rear-mounted RS-232 and RS-485 connectors allow for remote programming, weld schedule selection,
and data logging for SPC purposes. Data output provides the necessary process documentation for
critical applications and permits data logging for SPC purposes.
Appendix E, Communications in this manual lists all of the commands that the Control will respond to,
and instructions on how to format commands sent to the Control so it will respond properly.
The Control contains internal software that gives you a great deal of flexibility in the setup and use of
your welding system. The Control software displays various menu screens on the LCD, each containing
prompts telling you which of the Control's front panel controls to use in order to customize operating
parameters, set the Control for use in an automated welding system, and program communication
settings for use with data-gathering devices such as a host computer.
The following menu screens tell you how to set the Control's communication and data options.
However, to enable the Control to perform these functions, you must install the software from the
optional
HF25 Advanced Serial Datacom Communications Interface Kit , commonly referred to as "the
Datacom kit," in a host computer.

In the
MASTER
role, the Control will:
−
Send weld data to the host computer after each weld operation.
−
Send text data to a serial printer, providing a printout of the average voltage and
current values for each weld, generating a "paper history" of welds performed.
