Analog I/O Slave Unit Functions
Section 11-4
Setting Hysteresis
The Comparator Result Flag turns OFF when the value is lower than the hys-
teresis width (H or HH alarm occurs) or exceeds it (L or LL alarm occurs), as
shown in the following diagram. If the analog value fluctuates around the
threshold, and the flag repeatedly turns ON and OFF, set the hysteresis to
stabilize the flag operation.
OFF Delay
The time until the Comparator Result Flag turns OFF can be extended. For
example, even if the Flag is ON momentarily, the OFF delay can be set so that
the Master Unit can receive notification of the Flag’s status.
