This is a bit of a vague question, but I am just starting on this, and
wonder if anyone has ideas of where to start.
I have a program that controls some external equipment. It sends messages in
various flavours to cause the equipment to turn signals on and off, and
change voltages and such like.
Attached to this external equipment, is another piece of equipment that
responds to these changes in signals and voltages.
What I need to do is automate the way in which my program turns these
signals on and off, and changes voltages in the external equipment. I also
need to do it in such a way that it is configurable without changes to
source code.
My first thoughts are towards some kind of script that I interpret and use
to determine what actions my program must take. The script would need to be
flexible enough to allow me to specify what signals are controlled, in real
time, and what voltages are set and over what time period they should
change. It would also need to allow me to monitor status from the external
equipment in a given time frame to determine if actions had been successful
or not.
That is as far as I have got. Is this type of application familiar to
anyone, and does anyone have any suggestions regarding how to go about this?
Some examples of scripts that make this type of operation possible?
As I say, it is a bit vague at this stage, and this is probably not the very
best place to be asking, so if anyone knows where I would be better asking
that would be helpful too. Otherwise, any pointers welcome.
TIA

Hi Hal
We (the company I am working with) are the manufacturers of the external
equipment, so we have our own comms protocol for this. The equipment is
connected via a simple serial/USB link. you said the equip does all the voltage changing - depending on the signal
you send to it - and that equipment talks to (controls) other equipment -
It's actually the other way around: we send commands to the external
equipment, and it changes signals and voltages to the devices on the end.
The actual mode of communication is not so much the problem as we already
have that in place. It is the automation of the control that we are looking
at now, and from earlier suggestions it looks like the Command pattern is a
good avenue.
Do you have any experience of that pattern (or others) in this type of
application?
Sounds like a distributed control system (DCS) - common to PLCs and some
Instrumentation
You are on the right lines; it is actually ATE (automatic test equipment)
for use in a production test environment.

What methods of communication is available to the equipment ? TCP/IP?
Does the equipment connect through a hub to a lan?
The mfg should provide some info - like "if you send "X" signal - the
equipment wil do 'so-n-so' does the equip have a network card? can you
telnet to it?
This sounds interesting. but mo info

Hi Lar
Thanks for the link. However, it is not the UI that I need to automate, but
objects at a much more lower level. The user will see progress indications
on the screen of the schedule that has been automated, and be able to stop
and start it, repeat bits of it and such-like.
