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.

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.

ModBus on Windows

by Frank Cebreros

Hi, with Artisan 1.1.02 I get this error Modbus Error: writeSingleRegister() 'ModbusSerialClient' object has no attribute '_last_frame_end'@line 30440 and have no communication with my rs485 device. I have tried Artisan 1.0.0 on the same machine same interface and have no communication problems. Best Frank

Re: [Artisan-user] Temperature Offset Correction Formulas on ARTISAN V.1.1.0: A) Notifications B) Questions

by Frans Goddijn

> During real time roasting , is there any way that events (TP, FC etc) show up > on the specific time moments on BT curve, without having to press the respective events buttons? In the Events menu these can be active: Then, CHARGE and DROP are automatically marked as well as TP. FC can not be truly autodetected without a listening device. Some roasters have experimented with it. But you can use this: Then FC is marked at the temperature that you have established that FC usually happens. Frans

Is it a kind of interference? Looks to me as if you loaded a profile in the background (named "93 IVORY DARK 6 KILOS.."). The light blue light seems to indicate the DeltaET (RoR of ET) of that profile as it corresponds to the shakes of the ET of this background profile. You can decide not to show this DeltaET curve by unticking the DeltaET flag in the "Profile Background" dialog (menu Roast >> Background). M

Temperature Offset Correction Formulas on ARTISAN V.1.1.0: A) Notifications B) Questions

by electra dedoussi

Dear Marko, Dear Frans, Once more, many thanks for your great technical support. A) Notifications As a matter of fact, the probes have not changed, but remain the same, K type for ET and J type for BT. Concerning the absolute values, after comparing the indications on room temperature (30 Degrees of Celsius) between both instruments (AMPROBE TMD 56 and PHIDGET 1048), the following Artisan formula (ARTISAN V.1.1.0) was set, in order to obtain a temperature offset correction on BT value: Configuration/ Device/ Symb ET/BT: Y1: None Setting (ET Value) Y2: 1.11*Y2 (BT Value) Also: Configuration/ Device/ Phidgets/ Phidgets 1048/1051 Type 1 2 3 4 J K K K Then, real time tests took place with various coffee roasting profiles (attached files) and the temperature measurement system worked properly and accurately, because the above settings are kept in memory for all the already saved coffee roasting profiles. B) Questions l During real time roasting , is there any way that events (TP, FC etc) show up on the specific time moments on BT curve, without having to press the respective events buttons? l What is the meaning of the light blue curves that show up on the background of the IVORY CITY PLUS 6 KIL coffee roasting profile? Is it a kind of interference? Looking forward to your reply.

Re: [Artisan-user] In attention of Mr. Marko Luther from Electra Dedoussi: Question about temperature offset

by Marko Luther

Dear Electra, did you only change the meter (Amprobe => Phidget) or also the probes? Note that thermocouple are not very accurate on an absolute scale (thus there are specific and more expensive thermocouple classes that are better than normal once). RTD probes like PT100 are more accurate if you are interested in absolute values. In Artisan you can shift a profile loaded into the background up and down via the cursor keys or the Profile Background dialog (menu Roast >> Background). During recording you can apply any formula to a temperature signal by defining a symbolic formula. See the following posts for some documentation of this feature: https://artisan-roasterscope.blogspot.de/2015/10/signals-symbolic-assignmen… https://artisan-roasterscope.blogspot.de/2014/04/virtual-devices-and-symbol… To shift your BT values (during recording) by 10C up, you can enter the following formula x+10 under "BT Y(x)" (menu Config >> Device, tab 3 "Symb ET/BT"). Note that you can enter all type of non-linear mapping as symbolic formula here too. Marko > On 17.
