There are several tools that can be used to effectively identify and troubleshoot complex problems in industrial automation systems, including:


Programmable Logic Controllers (PLCs) and Human Machine Interfaces (HMIs): These devices can be used to monitor and control different aspects of an automation system, and can provide real-time data and error messages that can help to identify problems.


SCADA systems: Supervisory Control and Data Acquisition (SCADA) systems can be used to monitor and control industrial processes remotely. These systems can provide detailed information about the status of different systems and can be used to identify and troubleshoot problems.


Data logging and historian software: These tools can be used to collect and store data from different systems over time, allowing you to analyze trends and identify patterns that may indicate a problem.


Network analyzers and protocol analyzers: These tools can be used to monitor network traffic and identify any communication errors or issues that may be causing problems in the automation system.


OPC UA: OPC UA (Open Platform Communications Unified Architecture) is a communication standard for industrial automation that is used to ensure interoperability between different systems and devices. OPC UA clients and servers can be used to monitor and control systems, and to collect data for troubleshooting and analysis.


Remote Monitoring and Management systems: These systems allow you to monitor and manage your automation systems remotely, often through a web interface. This can be useful for troubleshooting and identifying issues that may not be immediately apparent when on-site.


Simulation Software: Some simulation software can be used to model an industrial automation system and run test scenarios, which can be very useful for troubleshooting, as it can help to identify potential issues before they occur in the actual system.


By using a combination of these tools, you can effectively identify and troubleshoot complex problems in industrial automation systems, and help ensure that your systems are operating at optimal performance.
