Hi all!
Thanks for developing Artisan! It's an amazing piece of software.
I am trying to configure a Watlow PM6 controller for Artisan Beta 4. I have limited PLC and controls knowledge, so please bear with me.
I have installed the requisite drivers for my 485 to usb converter. I am using RTD probes and can read the temperatures in the specified registers through modbus (Watlow modbus test program). I can configure and get Artisan to request the data from the Watlow registers and the Watlow communicates during each call for sample (at the correct intervals). Also, the Watlow is in Modbus mode, using the correct data map (map 2) and sends the data in lo-hi. Slaves are set to 1, reading from regsiters 360 and 450, baud rate set to 19200 and using the correct COM port (COM4 on my system).
I cannot get Artisan to display the temperatures read by the RTDs. It either displays nothing for both or seemingly random numbers which do not correlate. I'm not sure if there is an issue with my settings or if the Beta 4 has an issue with this specific controller?
Any help would be fantastic and much appreciated.
Best regards,Matt
Dear all,
The version 0.6 of Artisan is now available for Windows, OS X and Linux.
<https://code.google.com/p/artisan/downloads/list>
The most important changes and additions w.r.t. v0.5.x are as follows.
- Monitoring-only mode reporting readings on LCDs without recording
- Event sliders e.g. to control the Hottop heater and fan via the HT Roaster Interface
- Extended alarms triggered by time and temperature on any curve
- Flexible Modbus RTU support allowing temperature reading and device control
- Curve smoothing and spike filtering
- New localizations: Arabic, German, Greek, Spanish, French, Japanese, Norwegian, Portuguese, Turkish, Dutch, Chinese and Hungarian
- Windows installer, and icons on Windows and Linux
See <https://code.google.com/p/artisan/wiki/ReleaseHistory> for a detailed list of changes and the Artisan blog <http://artisan-roasterscope.blogspot.de> for details on some of the new features.

Hi John,
I can't speak for the TMD-56 , but I had terrible problems using a Fluke
hand held type K probe with ground loops. This is easy to determine with a
DMM on the probe by testing to see if there is continuity between any of the
leads on the probe and with the probe itself . The cheaper hand held probes
are sometimes not isolated. When I changed to an isolated probe (no
continuity) all my ground loop problems went away.
I also tried as an experiment using osPID which is also Arduino with an
isolated probe on my roaster which is very very noisy electrically due to my
using a VSD for my 3 phase motors.\ and it works fine.
Hope this helps
