IIoT Configuration Device Self Service Version MES 15.81 Revision F1  

 

 

 

 

Introduction

The concept of GGC stands for “Green Grass Computer”, the word: “Computer” also refers to any kind of device. This document will teach users how to configure, install, and deploy a GGC, as well as create and set up a Device Self-Service for establishing a connection between the computer (device) and the 42Q portal to send data (payloads).

 

Prerequisites

• Only Linux is supported for the computer or device to install the Green Grass Core. The related shell scripts and test code only work on Linux systems (Windows is not currently supported).
• Python 3.8 or higher must be installed and configured to run the test code.

Operating System and Software Requirements

• Linux kernel version 4.4 or later (Ubuntu 20.04 and CentOS 8.5).
• Java Runtime Environment (JRE) version 11 or greater (included in the installation script).
• Python version 3.8 for functions that use the Python 3.8 runtime (included in the installation script).

 

Cgroups Requirements

The AWS IoT Greengrass Core software currently only supports Cgroups v1, not v2. In order to satisfy AWS Greengrass Core dependencies as stated in the official documentation "Setting up AWS IoT Greengrass core devices"  (Setting up AWS IoT Greengrass core devices - AWS IoT Greengrass ), the system should be configured with the following Linux kernel parameters and restarted:

To enable these Cgroups options, boot the device using the following Linux kernel parameters:

[https://docs.aws.amazon.com/greengrass/v2/developerguide/troubleshooting.html#lambda-cgroups-not-mounted

Step 1:  sudo vi /etc/default/grub
Find GRUB_CMDLINE_LINUX, and add the following command to it.

• For Centos 8.5

cgroup_enable=memory cgroup_memory=1 systemd.unified_cgroup_hierarchy=0

Figure 1: Command 

IIOT command.png

• For Ubuntu 22.04

cgroup_enable=memory cgroup_memory=1 systemd.unified_cgroup_hierarchy=false

Step 2: Enter the command: sudo update-grub
Step 3: Restart the system. sudo reboot
Then check the Cgroup, response tmpfs is right.
 root@:~# stat -fc %T /sys/fs/cgroup/tmpfs
 

Adjusting Cgroup configuration

1. Edit /etc/default/grub - Find the line that starts with "GRUB_CMDLINE_LINUX=" and append or change the following values: cgroup_enable=memory cgroup_memory=1 systemd.unified_cgroup_hierarchy=false - Save the file
2. Apply the configuration change by running: update-grub
3. Restart the system
4. Verify that the Cgroup configuration has been set to v1 by running the following command and ensuring that the response is "tmpfs": stat -fc %T /sys/fs/cgroup/;

 

 

Network requirements

The Green Grass Core device  must be able to access the following endpoints through specific ports:

• https://www.amazontrust.com/repository/AmazonRootCA1.pem.
• https://d2s8p88vqu9w66.cloudfront.net/releases/greengrass-2.12.6.zip.
• greengrass-ats.iot.us-east-1.amazonaws.com. Ports: 443.
• .iot.us-east-1.amazonaws.com. Ports: 443.
• .credentials.iot.us-east-1.amazonaws.com. Ports: 443.

For more details on what traffic needs to be authorized and why, please visit the official AWS documentation.

The channels for this asset type should have the same value.  Channel: Optional, Each protocol or driver used in a server project is called a channel.  A server project may consist of many channels with the same communications driver or with unique communications drivers. A channel acts as the basic building block of an OPC link. This group is used to specify general channel properties, such as the identification attributes and operating mode.  The channel in the attribute is optional, but If the customer needs to use Kepware to change/update tag value from MQTT messages, you would need to enter the channel(same as the channel in Kepware) when defining the asset type.

• Download and unzip the greengrass package locally.

 

Figure 43: Edge device tab

 

• Ask the 42Q mes-support team to provide a palindrome client ID and a secret that can access the mes-API and PTSR database.
• Edit core_config.json and add ClientId and Secret as given below. 

{
    "MaximumUploads":"3",
    "PoolMaxWorkers":"10",
    "RetentionDays":"7",
    "ClientId":"****",
    "Secret":"****",
    "FileType":[
        {
            "SubFolder":"/",

                    "Parser":"panacim"
                }
            ]
        }
    ]
}
The ClientId and secret can also be defined in the settings. The ClientId and Secret correspond to the Token and Key on the Settings page. The Token and Key on the Settings page are site-level and will be applied to all edge devices within the site. The other parameters don’t require a change.

• Open the terminal, and install greengrass by executing the command: sudo sh ggcV2.sh

 

5. Test Steps:

• Put the (eg.panacim xml ) file into the /home/traceability/incoming folder (step 1 installed). If the XML file is uploaded successfully, then check the success folder.
