This manual covers the connection of the Dutch Master Roasters DMR roaster to Cropster's Roasting Intelligence.
Specifications
Requirements
- Ethernet cable
- To use the Dutch Master Roasters integration, the roaster's software requires the following minimum software versions:
- App version 5.x.x
- Backend version 5.x.x
- PLC version >= 2.35.
The software versions are shown in the Dutch Master Roasters app, in the bottom left-hand corner of the screen (can be seen in the first screenshot located below).
If your PLC version is less than 2.35, a manual update of the PLC software needs to be done by Dutch Master Roasters. For more information regarding the update, please contact info@dutchmasterroasters.com
Additional Requirements
- To be able to control the roaster using the Roasting Intelligence control sliders:
- The setting "Remote control" needs to be enabled in your Dutch Master Roasters App.
- The button "Roaster" needs to be turned on (lit up in green):
- In the Roasting Intelligence you can switch between the Gas Control slider and the Set Temperature Control slider using the "Auto" toggle:
- The Gas Control slider can only be used during the roast, and not in the preheating phase.
- The Set Temperature Control slider can be used in the preheating phase, and during the roast.
- Control of Drum Pressure and Drum Speed is only possible during the roast.
Please note:
The Gas Control slider in the RI does not correspond to the "Maximum burner rate" on the Dutch Master Roaster app. Currently, "Maximum burner rate" cannot be controlled with the RI.
When the Gas Control slider is shown (Auto toggle in RI is disabled), the roaster's PID is disabled and thus, the Air Temperature Set Point has no effect, allowing you to control Gas manually with the Gas slider.
When the "Set Temperature" slider is shown (Auto toggle in RI is enabled), the roaster's PID is enabled and thus, the Air Temperature Set Point can be controlled from within the RI.
