Batch Counting (batCH)
Counting Up / Command Counting Down (Ud A)
Batch Counting ( bAtCH )
In Batch Counting, count setting value SV controls Output 2 which will turn ON momentarily for the time set
in the output pulse width parameter ( tout2 ) or will be maintained ON depending on the output mode selected.
Count setting value BATCH SV controls Output 1which will be maintained ON.
Input Mode:
Counting Up / Command Counting Down ( Ud A )
With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will increment the count
present value PV by 1.
With the input signal ON at input CP2, each leading edge of the input signal at CP1 will decrement the count
present value PV by 1.
Output Modes:
Mode F ( F )
When the count present value PV counts up or counts down
to the count setting value SV, Output 2 will turn ON and the
batch count present value BATCH PV will increment by one.
The count PV will continue to increment or decrement with
each input signal.
The leading edge of a "reset" input signal at RST1 will turn
OFF Output 2, reset the count PV to 0, and prohibit an input
signal from incrementing the count PV. The trailing edge of the
"reset" signal at RST1 enables counting to begin.
When the BATCH PV counts up to the BATCH SV, Output
1 will turn ON. The leading edge of a "reset" input signal at
RST2 will turn OFF Output 1, reset the BATCH PV to 0, and
prohibit an input signal from incrementing the BATCH PV.
The trailing edge of the "reset" signal at RST2 enables counting
to begin.
The "reset" signal minimum pulse width is set by reset pulse
width parameter ( rtSr ) or DIP Switch 8.
