Support for alarms has been around for quite a while and is in heavy use by some. More recently I got asked how to define an alarm that should be triggered 30s after the FCs (First Crack start) event.

FZ-94 (4) – Taking Control
Now that Artisan can talk to the drive controllers, it is not only possible to read the drive speeds, but also to control the drive speeds. However, that needs some further configuration changes on the drive controllers as well as some additional setup on the Artisan side.

FZ-94 (3) – Connecting the Drives
The FZ-94 comes with two Delta VFD-L drive controllers often referred to as frequency drives. One controls the drum speed, the other the air flow via the fan speed. Both are operated manually via a dial. While Artisan can log roasts automatically by reading the three temperature values from the machine via its RS485/MODBUS connection, the drum speed and air flow, both of which have a considerable influence on the resulting roast, have to be manually marked via some user defined buttons or sliders.
