[5] Alarm Display Function (ZM80 function)
This paragraph is explained the alarm display that added [1] Sampling Mode Typs on page 28 in
this book (page 34 to 42).
Operation envitronment in alarm display
Bit set/reset information that is stored in the internal buffer (or memory card) is displayed as a
message. This function resembles [Bit Sampling], but it has some special characteristics as
shown below.
It is possible to determine whether or not the error is a first cause error and display it.
When monitoring bit set/reset, you will notice that the setting of some bits (first cause) cause
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.
For details on the
normal operation
bit, refer to page
12-6.
Normal operation bit (reset when an error occurs)
ON
Error No. 1 bit (first cause)
OFF
Error No. 2 bit
OFF
Error No. 3 bit
OFF
It is possible to distinguish between error No. 1 and the other errors.
Ex.) When a belt conveyor error occurs
(2) 1st sensor error
(3) 2nd sensor error
(Advance direction)
(1) 2nd roller error (first cause) = conveyor stop
(1) is the cause of errors on (2) and (3). In this case,
(1) is called the “first cause.”
S: Normal operation bit (reset when an error occurs)
ON
A1: 2nd roller error bit (first cause)
OFF
A2: 1st sensor error bit
OFF
A3: 2nd sensor error bit
OFF
