Hi Marko,
Apologies, I mislead you last night by sending a screenshot of artisan when
it was disconnected. I don't have a noisy environment, no issue with the
modbus USB cable. Both it and the Phidget one are shielded. Heres a more
instructive screenshot, still no dice even with modbus set to dummy
Thanks,

Dear Ben,
I can see from the screenshot that the 1048 got first attached but soon
after again detached. Thus Artisan cannot access it any longer. Attach and
detach of modules is handled by the Phidget driver. I can only guess that
your USB connection is "weak". So either the cable is rotten or you are
working in a highly EMV spammed environment. USB wires easily catch EMV and
this breaks communication. I assume the Phidget driver observes
communication errors to the module and detaches it. Do you have un-shielded
motors running next to the TC or USB wires? The cause could also a low USB
voltage. You could try to put a powered USB hub inbetween the Phidget and
your computer. Note that this is only to check for the USB power situation
as a powered USB hub introduce quite some noise to the data lines via
different grounding levels. Do you run your computer from battery or
powered?
All external to Artisan. You could try to set the main device to DUMMY
(thus not connecting the MODBUS part) and see if this improves the
situation.

Hi Marko, many thanks for the prompt response. yes i have the current
v22 driver
installed, build 1.4
when i open the phidget control panel (with artisan off since only one
program can
access at a time) I can see the temperature read by channel 0,
its a real reasonable number
Thanks,
Ben

Correct
My confusion comes from the ports configuration
- The modbus settings have their own tab, that all works
Exactly

this mean its that appropriate place to specify the phidget connection?
Well, it should read "for non-modbus serial devices, not Phidgets"

Phidgets do not need any serial setup. They communicate natively through
USB (not
serial over USB).

the
little notification bar above "Roaster Scope" shows that its
connected. However when I click the ON button, the modbus temps show in
the LCD, but my BT2 shows as -1.0
what am I doing wrong?
Did you install the current Phidgets driver (which is v22) from
phidgets.com?
Artisan communicates to the Phidgets via this driver.
Just install that driver for your platform and you should good to go.
Best,
Marko
