(b) Alert delay count setting
The system is set in the alert status when the measured value (PV) that has
reached the alert set value remains in the alert range until the sampling
count becomes equal to or greater than the alert delay count.
An alert dead band can be set in Alert delay count (buffer memory address:
165).
Example: When the alert delay count set to the input upper limit alert is 5,
the system is not placed in the alert status if the sampling count is
4 or less.
