Giesen (from February 2018 onwards) - Roasting Intelligence (RI) Setup

This manual covers the connection of a Giesen roast machine built after February 2018 to Cropster's Roasting Intelligence.

RI4 is not available on Giesen's built-in Siemens panels. These panels are not powerful enough to support RI4's advanced features. If you have one, you will need an external computer to access these new features.

This setup manual only applies to machines manufactured after February 2018. If the manufacturing date of your machine is between June 2014 and January 2018 click here to go to the correct setup manual.



Supported measurements

    Establishing a connection to the machine

    1. Go to Account > Preferences > Machine tab.
    2. Select the Roasting machine you would like to connect from the drop down menu (e.g. Giesen W15A)
    3. Select Giesen PLC from the drop-down for all measurements.
    4. Click on the gear () icon to open the PLC IP-Settings.
    5. Enter the IP address of the roast machine according to the type:
      • WPG/WPE:
      • W1A/W1E:
      • W6A/W15A:
      • W30A:
      • W45A/W60A:
    6. Select the Drum speed unit according to Giesen's displayed Drum speed unit (i.e. HZ, RPM). We recommend to adjust the Drum speed unit to your preferred unit both on RI, and the Giesen display. Please reach out to directly to Giesen for assistance changing the unit on the Giesen display.
    7. Click Save to confirm the changes. The RI requires a restart to apply the settings.

    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.

    Learn more about how to:

    Giesen Drum speed control: set a roast with recorded Drum speed data as the reference and begin replaying your recorded Drum speed changes!

    When using Replay assist... 

    • Do not use any other temperature controlling software in parallel. Any gas/airflow/drum speed changes from a concurrent client disables Replay assist for the remainder of the roast. 
    • We recommend to replay (reference) roasts with logged drum speed data that matches your Giesen's currently set drum speed unit.
      • For example: if your Giesen machine is set to rpm (or Hz), we recommend that the logged drum speed data for the reference was also recorded in the same drum speed unit. The RI will replay the values from the reference under the assumption that the unit of the reference is the same as the unit currently configured on the Giesen machine.


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

    • Is the static IP address configured correctly?
    • Is the, according to the machine type, correct IP address entered?
    • Is the manufacturing year of the roast machine after February 2018?

    If the RI indicates Source connected but the measurements on the right hand side show -1.

    • The Giesen roaster is not yet unlocked. Go to the Entering the unlock code-section of this manual for more information. 

    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.
