Hello everyone, I am working on a project that utilizes the 1769-HSC module, which is installed in a 7-slot chassis. After configuring the module and powering it on, I noticed that the module's OK indicator is flashing red. Upon inspecting the program, I discovered that for local:7:I.fault, all bits are set to 1. However, I haven't cleared the fault, nor can I find the corresponding error code. The data does not seem to suggest where the fault originated. I would appreciate any assistance in identifying the source of the fault or guidance on where to locate the error code within the program. Thank you! Attached are images of the alarms for your reference.
If you encounter a flashing red indicator, it signifies a recoverable fault. To address this issue, you may need to reconfigure the system, reset it, or conduct an error recovery process. For detailed information, please refer to the section on Non-critical and Critical Module Errors found on page 113. Additionally, the OK indicator will flash red in response to all error codes listed in the Configuration Error Codes table on page 117. We hope this information is helpful to you. Best regards.
Hello Gclshortt, Thank you for your assistance. I have the specifications for the 1769-HSC module, and I understand that the information on page 117 pertains to error codes and extended error information. However, I am unable to locate the relevant error code within the program. Could you please guide me on how to find the error code in the software? I appreciate your help and look forward to your response. Thank you!
The module is assigned a distance rating of four, indicating that it needs to be located within four modules of the I/O bank's power supply unit.

Answer: A1: A flashing red OK indicator on the 1769-HSC module generally indicates a fault condition. This could be due to configuration errors, connection issues, or hardware malfunctions. It's important to check the module's fault diagnostics and error codes to determine the specific cause of the issue.
Answer: A2: To identify the source of the fault, you should first review the program and examine the local:7:I.fault bits. Since all bits are set to 1, it suggests a possible configuration error or a communication problem. Additionally, you can refer to the module's manual or use the programming software to check for diagnostic information and specific error codes that might give more detailed insights.
Answer: A3: Error codes for the 1769-HSC module can typically be found in the programming software's diagnostics or error logs. Referencing the module's manual will also provide explanations for various error codes. If the software does not show the error codes directly, ensure that the module is correctly configured and connected, and consult the manual for troubleshooting steps.
