Operating Mode Features<br />
The Z Gate/Reset Terminal will operate in one of four modes when<br />
the Store Count feature is in use. The four figures below detail the<br />
operation in each mode.<br />
Store Count Mode 1: Store/Continue<br />
In mode 1, the rising edge of a pulse input on the Z Gate/Reset<br />
terminal will cause the current counter value to be read and stored in<br />
the Read Data file. The counter will continue counting. The stored<br />
count will be available in the Stored/Accumulated Count word. The<br />
stored count information will remain until it is overwritten with new<br />
data.<br />
