*3 The special relay 07370 to 07377 are special relay, which are turned ON when detected in self-diagnosis.
In the event of abnormality, the kind of trouble is known by monitoring the special relay through support tool,
host communication, or data link. (The special relay is turned ON in the event of abnormality, but I/O processing
is not executed in the event of abnormality, and hence it cannot be taken out of the output.)
*4 The power source error is stored when the power source is turned ON even in normal state.
Note: If the JW300 detects an error during an operation using its self-diagnosis function, it stores the error code.
In addition, the operation status, stop output, indicator (FAULT etc.), and special relay status will be as
follows:
- If the error condition is removed before the watchdog timer times out (300 ms), the condition of the JW300
will not be as shown in the table above.
- If the error status lasts longer than the watchdog timer time (300 ms), the condition of the JW300 will be
as shown in the table above.
