Thanks for the reply. I've used Artisan with other devices/connections and it's
The default is 9600 but I've tried both and had no luck with either. The 19200 was
just the latest setting.
It did take quite some time before Artisan would even talk to the Watlow. I kept getting a
"no answer" error at first. I have also tried leaving the baud rate for the
ET/BT & Scale tabs at their defaults and matched with the Watlow's setting.

thanks for testing Artisan. Hard to say what is going wrong here. Could be a
communication issue. Isn't the baudrate of that device by default set to 9600

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
Any help would be fantastic and much appreciated.
