IMF Control Integration - Roasting Intelligence (RI) Setup (beta)

This manual covers the connection to IMF roast machines with control capabilities to Cropster's Roasting Intelligence.

If you haven't been invited to participate in the beta program for this integration, but you are interested in participating and testing the feature, please sign up here.

Beta means that the features are being tested with a select group of users to help us identify minor flaws under everyday conditions that we cannot reproduce internally. Therefore, it will be necessary that you share feedback with us and let us know whenever you come across some unexpected behavior.



  • Ethernet cable.

Supported measurements

  • Bean temperature (°)

  • Burner temperature (°)
  • Inlet temperature [°]
  • Set temperature control (refers to Inlet set temperature) [°]

  • Custom (refers to Vortex) [%]

  • Custom control (refers to Vortex control) [%]

  • Airflow [%]

  • Airflow control

  • Drum speed [%]

  • Drum speed control 

Software version: In order to be able to use the IMF control integration, your IMF roaster requires a recent software version. IMF roasters manufactured from March 2023 onward should already be equipped with the required software version. If your IMF roaster was manufactured before March 2023, its software needs to be updated. The software update can be requested at IMF and includes a fee.


Setting up a connection

Via the computer 

  1. Connect the network cable to your roaster's Ethernet port 
  2. Connect the other end to the computer's Ethernet port.

Proceed with the Roasting Intelligence (RI) setup


      Roasting Intelligence (RI) Setup


      Installing the Roasting Intelligence (RI) software

      1. Download the custom version of Roasting Intelligence here.
      2. The Cropster installer leads you through all the installation steps.
      3. Open the RI by double-clicking the Cropster icon on the desktop
      4. Enter your username and password.
        The username is the email address your Cropster invitation has been sent to. Use the password you've generated when accepting the invitation.
      5. Click the Login button.

      Establishing a connection to the machine

      1. If you are setting up RI for the first time, click the Select machine button in the banner at the top or click Preferences > Machine > Configuration bottom left to access the machine preferences screen. 
      2. Select the Roasting machine you would like to connect from the drop down menu. If the machine is not in the list you can add via the online platform.
      3. After selecting the machine all supported measurements will load. Change the order of the measurements by using the drag and drop icon  and moving it into position.
      4. Switch on the measurements you would like to enable and select IMF PLC from the dropdown. Repeat this step for all measurements you would like to enable.

        Make your measurement readouts more compact. Choose the size of your measurement readouts by selecting either the Small or Large view for display.

      5. Click on the Gear icon to open the PID settings.
        Default hostname/IP address:
        Legacy: Disable
        Temperature unit: select the unit shown on the IMF HMI screen

      6. Click Save to confirm the changes.
      7. RI will automatically restart after saving the changes. If the setup was successful you will be able to see temperature values on the right-hand side of the RI screen, after the restart.

      Control and Cropster Replay: In order to be able to use Cropster's control sliders with your IMF roaster, control needs to be enabled in the settings on your roaster's HMI screen:

      • Press the gear icon and the right arrow to get to the 2nd page of the settings screen

      • Enable the setting "Cropster - Enable Roasting"

      • Disable the setting "Cropster - Burner (0 = IMF; 1=CROPSTER)", as controlling the burner set temperature is currently not supported by the IMF integration for Cropster.

      Please note that controlling Set temperature, Vortex, Airflow and Drum speed using Cropster Roasting Intelligence is only possible if the roaster is in roasting phase.

      Between batches the roaster needs to be controlled using the roaster's HMI screen. The control sliders in Cropster Roasting Intelligence are not effective between batches and do not reflect the control values set on the roaster's HMI screen.


      There are two ways to control the inlet temperature of the roaster using Cropster:

      • If the “Auto” toggle on the control slider is disabled, the opening of the mixing valve (Vortex) can be controlled directly in the range 0-100%.

      • If the “Auto” toggle on the control slider is enabled, the set temperature of the roaster’s inlet temperature controller can be controlled in the range 0-550° C.

      The replay assist feature can be used for “Vortex control” and “Set temperature” control curves as usual. Please note that “Set temperature” is only replayed if the “Auto” toggle is enabled. Likewise, “Vortex control” is only replayed if the “Auto” toggle is disabled.


      If you prefer to control the roaster using the HMI screen of the IMF roaster's , please make sure to disable the setting "Cropster - Enable Roasting" in your roaster's settings screen.

      Please note that the control values set on the roaster's HMI screen are not reflected in the Roasting Intelligence. Therefore, if you want them to be the same, you need to set the same setpoints in both the roaster's HMI and Cropster RI.

        Note: Customize your RI user preferences

        If the RI indicates No source connected and/or you cannot see any measurements, please check the following: 

        • Are the IP address and temperature unit set properly in the Machine settings?
        • Did you disable Legacy?

        For further assistance, please create a support ticket by clicking the Support button in the left lower corner of the app. A Cropster support rep will get in touch with you.

        Congratulations! You have successfully set up the Cropster Roasting Intelligence!
