GE VMIVME-7592 Gas turbine input module

In mode 1, store/continue (1.4), the leading edge of a pulse input on the gate/reset terminal will cause the current value in the counter to be read and stored. The counter will continue counting. The stored count will be available in the block transfer read file. The stored count information will remain in the block transfer read file until it is overwritten by new data.In mode 2, store/wait/resume (1.5), the gate/reset terminal provides the capability to inhibit counting when the gate/reset input is high. Counting resumes when the input goes low. Mode 2 does not reset the counter, although it does store the count value.

In mode 3, store-reset/wait/start (1.6)

 the rising edge of the pulse on the gate/reset terminal causes the counter to stop counting, store the current count value in the block transfer read file and reset the count to zero. The counter does not count while the input pulse on the gate/reset terminal remains high. Counting resumes from zero on the falling edge of the pulse at the gate/reset terminal on the rising edge of a pulse input at the gate/reset terminal will cause the counter to store the accumulated count value and will reset the counter to zero. The counter continues counting, and the stored count is available in the block transfer read file.

show the store count feature

 operating on the rising edge of the gate/reset pulse. The user has the option of selecting these same features using the falling edge of the gate/reset pulse. This selection is made through the gate invert bit as explained in chapter 4. The gate invert bit is active in the store count, continuous/rate and period/rate modes. The stored count values are saved in words 11 through 18 of the block transfer read file
