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