7.4 Error Codes
7.4.3 Error code list of the errors that the remote I/O station detects as well as a CPU module does
7.4.3 Error code list of the errors that the remote I/O station detects
as well as a CPU module does
The MELSECNET/H (MELSECNET/10 mode) remote I/O station performs some operations that are the same as
those of a CPU module. Therefore, the same error codes
*1
are detected in the MELSECNET/H (MELSECNET/10
mode) remote I/O station and a CPU module.
When an error occurs, the corresponding error code
*2
can be read using GX Developer.
For detailed operation of GX Developer, refer to the operating manual for GX Developer used.
*1 The error codes of a CPU module are classified into three levels.
Whether the CPU module continues or stops its operation can be checked in the Remote I/O operation status column of
the Error code list.
*2 If an error that is not on the error code list is detected, please consult your local Mitsubishi representative.
• Minor error: Errors that allow a CPU module to continue its operation, such as a battery error
(Error code: 1300 to 10000)
• Moderate error: Errors that may cause a CPU module to stop its operation, such as a WDT error
(Error code: 1300 to 10000)
• Major error: Errors that may cause a CPU module to stop its operation, such as a RAM error
(Error code: 1000 to 1299)
