EXPERT PLC PROGRAMMING ERROR IDENTIFICATION & REFERRAL SERVICES

Are you experiencing unexpected behavior with your PLC system that you suspect might be due to a programming error? While ROC Industrial does not directly modify or debug customer PLC programs, we offer expert diagnostic services to help identify if a programming error is the root cause of the problem. If we determine the issue is within your PLC code, we can then refer you to a qualified PLC programming specialist.


Understanding PLC Programming Errors


PLC programs (ladder logic, structured text, etc.) control the behavior of your automation system. Errors in these programs can lead to a wide range of problems, including:


  • Incorrect machine operation.

  • Unexpected shutdowns.

  • Safety hazards.

  • Communication errors.

  • I/O malfunctions.


Important Note: ROC Industrial's expertise is in PLC hardware repair. We diagnose and fix physical problems with the PLC itself, its power supply, I/O modules, and communication interfaces. We do not offer PLC programming services or code modification.


What We Can Do:


  • Identify Programming Errors as the Source: Our technicians can use diagnostic tools and their understanding of PLC operation to determine if a problem is likely caused by a programming error, rather than a hardware fault. This saves you time and money by preventing unnecessary hardware repairs.

  • Read Fault Codes and Diagnostics: We can interpret fault codes and diagnostic information from the PLC that may point to programming issues.

  • Isolate the Problem: We can help determine if the problem is within the PLC program, the HMI program, or elsewhere in the system.

  • Refer to Qualified Programmers: If we confirm the issue is a programming error, we can refer you to a trusted network of qualified PLC programming specialists who can modify and debug your code.
