Warning output function
(1) Process alarm
(a) Warning occurrence
When the detected measured temperature value is higher than or equal to the
process alarm upper upper limit value, or lower than or equal to the process alarm
lower lower limit value (when the value enters the warning output range), a
warning occurs.
When a warning occurs, "1" is stored to the bit of the corresponding channel in the
Warning output flag (Process alarm) (Un\G47), Warning output signal (XD) turns
ON, and the "ALM" LED turns on.
process alarm upper upper limit value, or lower than or equal to the process alarm
lower lower limit value (when the value enters the warning output range), a
warning occurs.
When a warning occurs, "1" is stored to the bit of the corresponding channel in the
Warning output flag (Process alarm) (Un\G47), Warning output signal (XD) turns
ON, and the "ALM" LED turns on.
(b) Warning clearance
After a warning occurs, when the temperature value is lower than the process
alarm upper lower limit value or higher than the process alarm lower upper limit
value (when the value returns to within the setting range), the warning is cleared.
When the warning is cleared, "0" is stored to the bit of the corresponding channel
in the Warning output flag (Process alarm) (Un\G47).
Warning output signal (XD) turns OFF only when the values for all channels return
to within the setting range.
alarm upper lower limit value or higher than the process alarm lower upper limit
value (when the value returns to within the setting range), the warning is cleared.
When the warning is cleared, "0" is stored to the bit of the corresponding channel
in the Warning output flag (Process alarm) (Un\G47).
Warning output signal (XD) turns OFF only when the values for all channels return
to within the setting range.
