Subtract Command by software - PLCS HSC

Buffer Memory (ch1: 1EH / ch2: 3EH)

If 1 is written to buffer memory when a HSC module is counting in 1-phase input, the module can count down.

To count down by software, 1(1-phase 1-multiple Phase B software input) or 3(1-phase 2-multiple Phase B software input) is to be inputted to buffer memory for pulse input method (ch1:1DH, ch2:3DH).

As a set value is stored in EEPROM, the HSC module is operated as previously set value even though the power is on and off.
