Modbus Error: Read float() hex() argument can't be converted to hex@line 30521

by Randy＠BuckeyeCoffee.com

Dear Artisan user group; I have received an error I have not seen before using a Mac with the latest solfware : Sierra with a 64 bit system. We have installed the CP210 driver with our data logger using Omron controls. Here is a screen shot: Modbus Error: Read float() hex() argument can't be converted to hex@line 30521 Could it be we have the wrong driver installed? We use to use the FT232 driver but data driver was upgraded to a new model that has worked with the CP210 driver on most models (this data logger is setup for future use with Bluetooth capabilities) Thank You; Randy Harper

thermocouple discrepancy and other phidget settings

by Dustin Fluke

I'm relatively new to artisan. Been using RoastLogger for years but now that I have my phidget 1048 I don't need the camera/ocr feature anymore. I haven't been able to locate the help file or information about the settings under Config-Device - Phidgets tab. For instance, Async check boxes, raw data, change etc. I've found everything on the github page, but maybe I just haven't been successful in pinpointing the proper area to look. Secondly- I'm roasting on a Diedrich IR-24, which has a thicker J thermocouple than the one I've hooked up to artisan, which is a K type 1/8in I purchased here: https://www.automationdirect.com/adc/Shopping/Catalog/Sensors_-z-_Encoders/T emperature_Sensors_-a-_Transmitters/Thermocouple_Sensors/Probes_(with_Lead_W ire_Transition)/THMK-T06L06-01 The temperatures are around 30 degrees F higher on the thinner K thermocouple than what the roaster is reporting, even though my thermocouples in the roaster are mounted next to each other (didn't want to piggyback on BT of the roaster to phidgets) Does anyone have any experience in this area? Perhaps the simple fact that the probe is thinner means the readings will be different, but I do not know. It would appear that the readings on the roaster are accurate while the other is much hotter. Just getting started, and appreciate any guidance.

On Idle Noise

by Marko Luther

Dear all, I received many complaints on noisy RoR signals over the year. The ongoing work of Scott Rao and a broken TC made me reconsider my own roast logging setup. As I had collected many different meters and probes over the years, mostly for development purpose, I wonder which one I should best install in my machine. My goal was to minimize both, the signal to noise ratio as well as the introduced signal delay, especially for the RoR. Thus I came up with a setup that would allow me to compare different setups on the amount of idle noise they produce. Details are here: https://artisan-roasterscope.blogspot.com/2019/03/on-idle-noise.html I switched from TCs to RTDs for reasons detailed in the post and I am quite happy with my new setup, Marko

Multiple VINT hubs/1136 gone from support devices page

by Craig Seko

Hi everyone: My roaster is apart for mods and it is getting to the point that I could take advantage of a second another VINT hub. I just want to check if that is possible, please. Also, I noticed that there is no mention of Phidget 1136 (diff. air pressure) on the supported devices page. Has support been dropped? Kind regards, -Craig -- --- - Craig Seko

Re: [Artisan-user] Just downloaded 0.9.7, get error

by Frans Goddijn

The info you provide is very terse. “SF6” is probably http://www.sanfranroaster.com/sf-6lb <http://www.sanfranroaster.com/sf-6lb> And “Watlow" I assume to mean http://www.watlow.com/products/controllers/temperature.cfm <http://www.watlow.com/products/controllers/temperature.cfm> My hunch is you maybe just connected the cables without making sure that variables like baud speed, even/uneven, parity, stopbits are all set exactly the same on both ends. SF should be providing that info / assistance in their manuals / service desk.

phidget ambient?

by Frans Goddijn

Dear Marko, here the Phidget ‘ambient’ devices seem not to be communicating… I just spotted this late tonight. Tomorrow I’m off for 2 days. It’s no a problem here but maybe it’s not just my system where this stopped. F
