Setting Initial Counter Value

In order to utilize the alarm function, users have to set a high-alarm limit

value and/or a low alarm limit value, and a initial value to fulfill the

requirements for a basic alarm setting.

Overflow Value

Overflow value is the number of times the counter value exceeds the

Max/Min values you specified. When the counter value exceeds Maxi-

mum value, the overflow value increases; when the counter value goes

under Minimum value, the overflow value decreases. Besides, when the

counter value runs beyond the range of Max/Min value, it will continue

counting from the initial value. Furthermore, if users want to check the

counter value to see if it is higher or lower than the Max/Min value, they

can use the "ReadOverflowFlag" library to gain a readout of the over-

flow value.
