It is possible to display errors with distinction between the “first cause” and
“others.” When monitoring bit activation (ON/OFF), you will notice that the
setting of a bit (first cause) causes secondary and tertiary bits to be set as
well. When this occurs, it is possible to distinguish which bit was set first and
which bits were set after, and thus it is possible to specify which bit is the first
cause bit.
Example: When a belt conveyor error occurs:
By marking the first cause with an asterisk (
∗
) when the error messages are
displayed, you can distinguish the first cause error from the other errors.

Normal operation bit
Error No. 1 bit (first cause)
Error No. 2 bit
Error No. 3 bit
It is possible to distinguish between error No. 1 and other errors.

(Advance direction)
1. 2nd roller error (first cause) = conveyor stop
Errors 2 and 3 are triggered by error 1.
In this case, error 1 is called “first cause.”
