*1: The operation status can be changed to "Continue" with the parameter setting in GX Developer.
(The default is set to "Stop".)
*2: This option can be set "not checked" (set "checked" by default) with the parameter setting of GX Developer. Also, this option is not
checked while SM251 is on.
*3: This option can be set "not checked" (set "checked" by default) with the parameter setting of GX Developer.
*4: In multiple CPU systems, when the serial numbers of all the CPU modules (first five digits) are "07032" or later, this error is detected from
the CPU No.1 only.
*5: The CPU module function version B or later supports the detection of this error.
*6: Since this diagnostics indicates CPU module status, the error message is not displayed in the "Current Error" field on the PLC
diagnostics screen of GX Developer.
This error is displayed in the Error history field only.
When the Redundant CPU is used, the details of an error occurred in the other system are stored in the special relays
(SM1610 to SM1626) and special registers (SD1610 to SD1636) except when:
• the other system is during off, reset, or hardware failure,
• "WDT ERROR" (error code: 5000, 5001) is detected, or
• tracking cable has an error (not connected, disconnection, or failure).
