Introduction

This project aims to develop a SCADA system using Node-RED for monitoring and controlling a Modular Production System (MPS). The project includes integration of multiple PLCs using FINS UDP and Modbus TCP protocols.

Description: The image above represents an overview of the system architecture, illustrating the integration and flow of data between different components in the SCADA system. The Omron CP1L-M30DR-A PLC uses the FINS UDP protocol, while the Siemens S7-300 PLC uses the Modbus TCP protocol. The PLCs are connected to a TP-Link WR840N router using Ethernet, which then sends the data to the MTU/PC. The Node-RED dashboard is used for monitoring, and InfluxDB is used for data storage. For more detailed information regarding this project, refer to the document.

Maintenance Guide

The maintenance guide provides detailed instructions on how to maintain the Node-RED MPS SCADA system.

Regular Maintenance

1. Check Node-RED Flows: Ensure all flows are running without errors.
2. Update Dependencies: Regularly update Node-RED and installed nodes.
3. Backup Flows: Backup the current Node-RED flows.
4. Inspect PLC Connections: Verify all PLC connections are stable and functioning.

Troubleshooting

1. Node-RED Issues: Refer to the Node-RED logs for error details.
2. PLC Communication: Check the PLC communication status and logs.
3. Network Issues: Ensure the network connectivity is stable and reliable.

Standard Operating Procedures (SOP)

This section includes the SOPs for operating and managing the Node-RED MPS SCADA system.

Starting the System

1. Power On: Turn on all PLCs and network devices.
2. Launch Node-RED: Start the Node-RED server.
3. Load Flows: Open the Node-RED dashboard and load the required flows.

Shutting Down the System

1. Stop Node-RED: Gracefully stop the Node-RED server.
2. Power Off: Turn off all PLCs and network devices.

Node-RED JSON Code

This section contains the JSON code for the Node-RED flows used in this project. The Node-RED flows are located in the Node-RED folder.
