Nilden Tutular, Volkan Balikci, Uygar Zubari [Eldor Corporation] | MQTT - Machine Data Collection | InfluxDays NA 2021

MQTT – Machine Data Collection
Collecting data from machines triggers our data-driven insights to predict breakdowns. Using Telegraf and Kapacitor for that aim creates magnificent data pipelines to help doing zero-break production.

  4. 4. © 2021  InfluxData Inc. All Rights Reserved. © 2021  InfluxData Inc. All Rights Reserved. Machine Data Collection with MQTT Architecture The data obtained by the Robot Controller, such as Torque, Temperature & Current, are sent to the PLC with the EtherCAT industrial communication protocol. This data is then sent to the MQTT Broker on the server with the MQTT communication protocol. The sent data is instantly listened by the Telegraf through the MQTT Broker . We have worked with many different types and brands of robots. In this presentation we wanted to share the details of our work with KUKA Industrial Robots. We use OMRON brand as PLC.
  5. 5. © 2021  InfluxData Inc. All Rights Reserved. © 2021  InfluxData Inc. All Rights Reserved. Details about Data Collection KUKA Industrial Robots have 6 axes. Therefore, the data we receive is separated on an axis basis. ▶ Each data has two subtypes. Average and Peak Values. The data (Torque, Temperature & Current) received from the Robot is sent to the PLC with the EtherCAT (Industrial Communication Protocol). These data are made meaningful in PLC and transmitted to MQTT Broker in the form of JSON Data Format. Axis No Torque Temperature Current for (i=1; i<=6; i++) Axis Average Value Axis Average Value Axis Average Value Axis Peak Value Axis Peak Value Axis Peak Value

We publish it to MQTT broker with MQTT protocol . • Omron PLCs are used in our factory. That's why we made this project using Omron PLC’s . • In order to use the MQTT Protocol on the PLC side; First of all, • It is necessary to have an Ethernet card on which the Socket Service Functions of the PLC can be used. Because when using MQTT, it has to open a socket according to the TCP/IP standard and send the data to this socket with a topic . • Omron has created a library to PLC, which includes function blocks for MQTT Protocol and JSON Data Standard. ( A function block is a smart function with its own instances and memories.) Details about Data Collection
  7. 7. © 2021  InfluxData Inc. All Rights Reserved. © 2021  InfluxData Inc. All Rights Reserved. Mosquitto, Open Source MQTT Broker, is used as MQTT Broker. By the way, to briefly explain the MQTT Broker ; An MQTT broker is a server that receives all messages from the clients and then routes the messages to the appropriate destination clients. PLC and Telegraf are connected to MQTT Broker as MQTT Client. Here, the Broker acts as a server, making it possible to transfer data between clients . This Broker is installed on a Windows operating system computer. With the installation of this program, that computer turns into a MQTT Broker . The Broker's configuration is set to activate 1 port for up to 5 Robots for optimum data usage (Default 1883) . PLC publishes the data from the determined topic to the Broker. Obtains the data by listening to the broker from the same topic in Telegraf.

The next steps We have already configured these two technologies in order to predict our Robot’s breakdown times. We have 1-Click ML Architecture with Kapacitor on Chronograf and still trying to improve our TICK-Stack knowledge for using the same stack in other fields like sensor data.
