Program example
1. Displaying a fault number using an annunciator
When the program for external fault diagnosis shown below is created and the content of D8049 (smallest state relay
number in the ON status) is monitored, the smallest state relay number in the ON status from S900 to S999 is
displayed.
If two or more faults are present at the same time, the next smallest fault number is displayed after the fault of the
smallest fault number is cleared.
number in the ON status) is monitored, the smallest state relay number in the ON status from S900 to S999 is
displayed.
If two or more faults are present at the same time, the next smallest fault number is displayed after the fault of the
smallest fault number is cleared.

When M8049 turns ON, monitoring becomes valid.
If the forward end detection input X000 does not turn
ON within 1 second after the forward movement output
Y005 is driven, S900 turns ON.
If both the upper limit input X001 and the lower limit
input X002 are OFF for 2 seconds or more due to a dog
error, S901 turns ON.
The switch X004 is set to ON in one operation cycle of
the machine. If the switch X004 is not set to ON while
the continuous operation mode input X003 is ON in the
machine whose tact time is less than 10 seconds, S902
turns ON.
When one among S900 to S999 turns ON, M8048 turns
ON and the fault display output Y006 turns ON.
A state relay which was set to ON by the external fault
diagnosis program is set to OFF by the reset button
X007. Every time X007 is set to ON, an operation state
relay in the ON status with the smallest device number
is reset (set to OFF) in turn.
