Specifications

Requirements 

Ethernet cable

  • Network router with DHCP server capability
  • CR-series only: Cropster Replay Assist ready
    A Diedrich is Cropster Replay Assist Ready when a "Cropster Replay" button is shown from the machine's HMI display.

 All DR-series machines are equipped with Semi-Auto and are compatible with the control of Gas and Airflow.

Supported measurements

  • Bean
  • Exhaust
  • Inlet
  • Gas (%)
  • Gas control (%)
  • Airflow (%)
  • Airflow control (%) 


Setting up a connection

Your Diedrich roast machine may have a rear-end Ethernet port to connect the Ethernet cable from the machine to a network router.

If your machine does not have a rear-end Ethernet port, use the HMI display's LAN1 port instead.

Via the network router

  1. Connect the network cable to your roaster's rear-end (or LAN1) ethernet port.
  2. Connect the other end to your network router's Ethernet port.
  3. Proceed with the Network settings.
     

This connection requires a network router (DHCP server). Most home routers will have the DHCP server turned on by default.

 

 

Network settings

Identifying the IP address

Once the Diedrich has been connected to a network router, an IP address has been assigned to the roaster. 

  1. Go to the Diedrich's HMI display.
  2. Go to the setup screen and press the Refresh IP address button. 
  3. You will need to refer to the LAN1 IP address.
    You will need to input the LAN1 IP address from RI at a later step.
    The LAN1 and LAN2 IP addresses may differ from the image.
  4. Continue with the DHCP configuration for Windows or macOs:
     

DHCP configuration - Windows 7, 8, 10

  1. Navigate to the Control Panel > Network and Sharing Center or Network and Internet > Network Sharing Center.
  2. Click Change adapter settings. 
  3. Right-click on WiFi.
  4. Click Properties. 
  5. Select Internet Protocol Version 4 (TCP/IPv4). 
  6. Click Properties.
  7. Select the Use the following IP Address option.
  8. Select the Obtain an IP address automatically option.
  9. Click the OK button to submit your changes.
  10. Proceed with the Roasting Intelligence Setup.
 
 

 

DHCP configuration - macOS 

  1. Navigate to > System Preferences > Network
  2. Identify the Local Network that corresponds to your router. 
  3. Click on Details...
  4. Open the TCP/IP section.
  5. Open the Configure IPv4 dropdown menu and verify that Using DHCP is selected.
  6. Click the OK button to confirm the changes.
  7. Proceed with the Roasting Intelligence Setup.

Establishing a connection to the machine
 

The images below are for reference and may vary slightly from your screen.

 

 

Important details to keep in mind:

  • Before you start configuring your roast machine, ensure that you have added it via the online platform C-sar.
  • Only click Save after you've completed all the settings in Roasting Intelligence. 
 

 

  1. SelectPreferences > Machine > Configuration
  2. To choose the Roast machine, click on the dropdown menu in the Machine section.
  3. Click the + Add connector option to choose your connector from the dropdown list.
  4. Select Diedrich PLC from the dropdown. 
  5. Click Select to add the connector.
  6. Click the Gear icon in the Connector setup section to open and configure more settings.
  7. Select the following details:
    • Version: Select DR/CR series - Semi-auto/ZIII
    • Hostname/IP address: Enter the IP address of the roast machine according to the type in the LAN1 IP address as shown by Diedrich's HMI display.
  8. Click OK.

 

  1. Navigate to the Machine > Measurements tab. All supported measurements will be displayed.
  2. To activate the measurements, simply click the green toggle button.
  3. Enable the desired measurements and choose Diedrich PLC as the connector type.
  4. (Optional) Change the order of the measurements by using theDrag and Drop icon and move it into position.

 

  1. Navigate to the Machine > Slider controls tab.
  2. To activate the controls, simply click the green toggle button. Enable the controls you wish to activate.
  3. Choose Diedrich PLC as the connector type.

Troubleshooting

If Roasting Intelligence indicates No sources connected and/or you cannot see any measurements, please check the following: 

  • Is the machine connected via the rear-end Ethernet port, or the HMI's LAN1 Ethernet port?
  • Is the machine connected to a network router?
    • Is the network router DHCP-capable?
    • Did you verify the LAN1 IP address and input it as shown from Diedrich's HMI?

Connecting via a DHCP router

The router uses DHCP (Dynamic Host Configuration Protocol) to communicate with the Diedrich HMI. Because IP addresses are only leased (or borrowed), if you lose connection from the Roasting Intelligence, it is likely that:

  • The LAN1 IP address changed upon adjusting the connection to the router.
  • The lease time for the IP address reached its end, and hence a new IP address may have been assigned to the LAN1 port.

If you lose connection to the Diedrich, it will be important to check that the LAN1 IP address has not changed since the last time it was input into the RI's Machine settings.


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