Troubleshooting Flow Chart (PLC, DCS, SCADA Systems)
Troubleshooting Flow Chart
Who this is meant for:
This tool is meant to aid persons who must troubleshoot modern PLC, DCS, or SCADA control systems - but who do not have access or capability to utilize the online software monitoring tools.
In some cases, organizations restrict access to the software for various reasons (including some very valid reasons) - but this can make it challenging for the technicians tasked with troubleshooting these systems. This flow chart is meant to provide at least a starting pathway to logically proceed towards identifying the source of the problem.
Objective:
Admittedly, in some cases the problems must be solved by looking at applicable software. This flow chart attempts to exhaust the steps that are possible without the software and to verify field side functionality prior to digging into the logic. For many sites who utilize external vendors or other outside groups for this level of troubleshooting, these steps can help speed up the process for the external help and will likely reduce the number of times they are required.
Limitations and Customization:
This flow chart is somewhat assumptive and generic in nature. Systems that are less complex may be able to include specific instructions and tips based on types of inputs and common problems - but this is meant as a starting point to create such documents.
We do provide services such as creating customized troubleshooting flow charts and other system specific training aids, task guides, and other tools for primary training customers. Contact us for more information on this powerful approach to boosting the outcomes of your teams.
