The recent trend Industry 4.0 is the attainment of digital transformation in the factory floor enabling real-time decision making, enhanced productivity & flexibility in the manufacturing industry. As a part of our Industry 4.0 solution, we have recently built a MES (Manufacturing Execution System), an ultimate production monitoring & management software. This exemplary production-oriented tool monitors & tracks the entire production line providing visibility & transparency (in every aspect of production process) with the complete production control. MES collects real-time data from modern CNC machine, send it to the central server and perform analysis to make data-driven decisions & optimize production efficiency.
Why Bevywise IoT Platform?
The Internet of things (IoT) is always meant to solve sticky, physical world problems but the pathway to integrate such technology in building our applications is almost equally intricate and complex. But there are lot of application enabled platforms available in the market which can almost reduce your application building complexity. In that case, using Bevywise IoT platform as a base framework, we built our Industry 4.0 solution, MES software. This article will walk you through the paths of how the solution is built over Bevywise IoT platform & will potray the hacks used for IoT application development.
As I said earlier, there are plenty of IoT platforms available in the market but the configuration modules Bevywise has, makes it flexible for any application development and that makes it stand out from others. The complete details on these configuration modules are explained in the below sections.
In its more sophisticated form, Bevywise IoT Platform has these modules which makes it more powerful end-to-end IoT platform enabling developers to build faster IoT applications.
- Connectivity Layer
- Data Persister
- User Management & Data visualization
- Action management (rules engine )
- Analytics Engine
Let us see how we were able to build MES software with these modules.
First & foremost every application development needs a connectivity layer to make direct communication with the devices. In our Industry 4.0 solution, MES, we want to include connectivity as a part of the solution.
Bevywise IoT Platform with its connectivity layer brings different protocols such as MQTT, MQTT-SN & TCP into one interface ensuring accurate data streaming and interaction with all devices. By using this connectivity layer we could establish the connectivity of Industrial machines with our application via the communication protocol. We were able to send machine data via MQTT as Bevywise IoT platform by default supports MQTT as its communication protocol.
When we create any business applications, data persistence must be enabled to persist the data object variables in the server and to prevent them being lost between sessions. To be clear, in the context of storing data in a data store, the data survives or remains even after the process ends.
Bevywise IoT Platform has this functionality which persist the device connection entry into MySQL. However, we may also want to store the device data into other persistence layers. Hence, Bevywise supports storing device data into Elastic Search. With data persistence, the data stored both in MySQL and Elastic search is persisted to make it remain for further analysis.
This makes us get utilized with persister in our MES software. For example, some data in industrial organizations must be persistent.
That is, our MES software includes multiple fields in the set up process, a user must complete. Also the user is added by filling multiple fields. The information entered in such fields should exist and with the persistence enabled the information the user enters in those fields persist.
Literally, every application probably needs a database which acts as a repository to store the necessary data sets. Coming to our Industry 4.0 solutions we need a database to be integrated into it to store all the critical industrial information.
As said earlier, Bevywise IoT Platform supports storage of data in Elastic search. Also, the device connection will be stored in MySQL.
User Management & Data Visualization
The next fundamental element that every IoT application needs is the user interface. After we collect data from machines & store in DB, the next thing we need to do is to deliver the information to the end user / someone who is intended to proceed with the next step of the industrial process. This can be done via the user interface. This is the interface by which any industrial user communicates or interacts with the application. Also, we need to make sure that UI must visually represent the data which enables users to see patterns and observe trends from manufacturing dashboards where data is vividly portrayed through charts & graphs. And you know what?? our IoT platform makes it much easier for us as it supports custom dashboard functionality which permits to create multiple dashboards with 10+ pre-built widgets specific to any application. We were able to layout OEE metrics and other machine data in charts & graphs.
Further, the manufacturing industry will have multiple departments and each department will be handled by a certain set of users. It is not always right to provide each & every access to all users in the industry. Thus, it is necessary to manage each user by providing specific roles & permissions. In that case, Bevywise IoT platform empowers the service provider to administer & supervise multiple users & their access to and from various sectors. With its multi-tenancy architecture, employees can be given individual web access and login & can be provided with separate roles & permissions for each to carry out machine management & monitoring tasks.
The next key function is to bring data to life with rule-based event-action-triggers enabling execution of “smart” actions based on specific machine data. This is more like automating some actions based on the condition we set. For instance, alerting the production manager when a machine sits idle.
This is executed with a powerful condition-based rule engine of the IoT platform which helps the user to forward alert messages to the subscriber.
How we built MES over platform
The scalability, flexibility & end-to-end application framework of the IoT platform enables us to build MES software without touching the core side. We have used these modules to configure and develop our MES solution specific to the need.
In addition to these, we have made some changes to the analytic engine of the platform and in front end modules to develop the perfect MES solution for the manufacturers.
Every manufacturing industry now expects advanced analytics such as predictive analysis to foresee developments and respond to challenges & machine failures proactively. But this requires advanced techniques such as machine learning & artificial intelligence which needs aggregated data from machines to anticipate more accurately.
This is where analytics engine of Bevywise platform comes in. Analytic engine collects data stored in Elastic Search & aggregate it as needed. It executes data aggregation to summarize every 5 mins data and stores in it. Then the data will be displayed in reports as per the needs of users. The analytic engine of the IoT platform is purely based on devices.
We have made a few changes in it as we want to make this analytic engine work based on, production plan, shift & production process. For instance, MES software needs to display day, shift, monthly & yearly data in the form of reports. This requires data to be aggregated for every, day, month & year. A few changes in analytic engine have been done to execute such aggregation. Now, MES software will be able to provide shift, day, month & year wise production reports.
User Interface module
Manufacturing Industry requires data to be presented as OEE metric with other key performance indicators such as availability, performance & quality in a way to assist the manufacturers to come up with actionable insights. As our MES software tracks multiple machines & departments, the data should also be displayed in machine wise, unit wise and department wise OEE. The comparison of production plan set & the actual production target reached also needs to be displayed. Hence, the UI module has been configured to make these components available to the manufacturers in the visual form from the user interface itself. Thus we were able to develop our MES over Bevywise IoT platform faster & much easier breaking down all the application development complexities.
