Agenda

“Protocol Zoo”Where does it happen?Why?

Deep Dive Greengrass with IIoT

IIoT Extraction Design Pattern

Summary


Money Spent on IIoT


Results for Spending the Money?

Unable to link data together

96%of industrial

state data is not used

Data collected too

infrequently

39%of Manufacturers do not

regularly collect data

Data difficult to access

66%of industrial companies find data is difficult to

access

Why?SCM World/Cisco “Smart Manufacturing & the Internet of Things 2015”


Decades of this...

Custom / Proprietary Protocol

MQTT


OPC-UA with Grenngrass

from opcua import Client as OPCUAClientclient = OPCUAClient(url)

client.connect()rootNode = client.get_root_node()

rootNode.get_child(path).get_data_value()

iotclient.publish(topic="opcua/raw", payload=json.dumps(extractResult)

)

Load the library

Connect to the IIoT data source

Retrieve

Push to MQTT


Modbus with Greengrass

from pymodbus.client.sync import ModbusTcpClientclient = ModbusClient(host, port)

client.connect()

r = client.read_holding_registers(address, bytes)

iotclient.publish(topic="modbus/raw", payload=json.dumps(r)

)

Load the library


Retrieve

Push to MQTT


Raw TCP with Greengrass

import socketipclient = socket.socket()

address=(ip,port)ipclient.connect(address)

data = str(ipclient.recv(1024).decode("utf-8")

iotclient.publish(topic="qr/raw", payload=data)
