6.7.1 LED display for error
When an error occurs, the LEDs on the front of the CPU module light up and flash.
( Section 6.17)
6.7.2 Cancel the error
The CPU module can carry out the operations canceling errors in programs as long as the
error allows the program operations to continue.
The occurring continuation error can be checked by the bit which is turned "1" of SD81
(error factor). Error factor/continuation error corresponding to the bit number of SD81 is
shown in Table6.12.
(1) Error canceling procedure
Cancel an error with the following procedure.
1) Read out SD81 with GX Developer and check the cause of the current
continuation error occurring in the CPU module.
2) Eliminate the cause of the error.
3) Store the canceling error code in special register SD50.
4) Turn special relay SM50 OFF ON.
5) Again read out SD81 with GX Developer and check that the bit corresponding
to the current continuation error canceled is OFF.
