(Note-1) : CPU No. is stored in slot No. of the common information classification.
(Note-2) : Base No. in "common information classification code" of "error information classification code" is 0 : CPU base, 1 to 7 : Number of extension bases.
(Note-3) : Because a stop error or CPU No. except CPU No. that it was reset becomes MULTI CPU DOWN simultaneously, a stop error or CPU No. except CPU
No. that it was reset may store in the classification of error information depending on timing.
(Note-4) : When an error occurs in the Motion CPU and so on except PLC CPU, if a PC diagnosis is made in the CPU except PLC CPU from GX Developer via
PLC CPU, the error code "10000" is indicated.
(Note-5) : The Motion SFC error detection signal (M2039) turned on at the error detection (SV13/SV22). A self-diagnosis error flag (M9008) and a diagnosis error
flag (M9010) do not turn on at the error detection. The error code "10000" being set in D9008 is reset in the Motion SFC error detection signal (M2039)
ON
OFF (SV13/SV22).
(Note-6) : MOTION RUN LED turns off at the stop error occurrence. (The condition of RUN LED does not change.)
(Note-7) : Operating status of CPU at the error occurrence can be set in the parameter. (LED display also changes continuously.)
