Counting cannot be performed during reset/reset 1 input.2. If reset/reset 1 is input while one-shot output is ON, one-shot output turns OFF.3. If there is power failure while output is ON, output will turn ON again when the power supply has recovered. For one-shot output, outputwill turn ON again for the duration of the output time setting once the power supply has recovered.4. Do not use the counter function in applications where the count may be completed (again) while one-shot output is ON.26Multifunction Preset Counter H7CX-A(Counter Function)Total and Preset Counter OperationThe H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value.Reset/reset 1Total reset/reset 2Present value0999999Total count value0Note: The full scale (FS) for H7CX 4-digit models is 9999.• The total counter continues to count thetotal accumulated value when the presentvalue is reset using reset/reset 1 input(reset key).• The total count value is reset when thetotal reset/reset 2 input is turned ON.
If thereset key is pressed while the total countvalue is displayed, the total count value isreset. The present value is also reset atthis time.• The counting range of the total counter is−99,999 to 999,999 (−999 to 9,999). Thetotal count value returns to 0 when itreaches the full scale limit.Batch Counter OperationThe H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed.• The batch counter continues after countcompletion.• Batch output is held until batch counterreset is input.• When the batch counter reset input isturned ON, the batch count value is reset,and batch output turns OFF.• If the reset key is pressed while the batchcount value is displayed, the batch countvalue is reset and batch output turns OFF.The present value is also reset at this time.Reset 1Reset 2 (batchcounter reset)Set valuePresent value0OUT2Batch count set value(Sub-display)Batch count value(Main display)210OUT1 (batch output)Note: The above is for when the output mode is C.Note: 1.2.3.4.5.6.The batch count value is held at 0 during batch counter reset input.If the batch count set value is 0, batch count will be performed but there will be no batch output.The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models).Once batch input has been turned ON, it will return to the ON state after power interruptions.If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON.After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch countvalue.Multifunction Preset CounterH7CX-A (Counter Function)27Dual Counter OperationUsing the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed.
It is possible to specify a set value forwhich output turns ON when the set value matches the added or subtracted result.OUT1 and OUT2 turn ON and OFF simultaneously.Dual Count Calculating Mode = ADDDual count value = CP1 PV + CP2 PVDual Count Calculating Mode = SUBDual count value = CP1 PV − CP2 PVReset 1(CP1 reset)Reset 1(CP1 reset)Reset 2(CP2 reset)Reset 2(CP2 reset)Dual count valueDual count set valueDual count valueDual count set value00CP1 present valueCP1 present value00CP2 present valueCP2 present value00OUT1, 2Note: The above is for when the output mode is N.• The operation after count completion for the dual countervalue is determined by the output mode.• The CP1 present value is resetwhen reset 1 input is turnedON and the CP2 present valueis reset when reset 2 input isturned ON.• If the reset key is pressed whilethe dual count value, CP1present value, or CP2 presentvalue is displayed, all of thepresent values are reset andoutputs turn OFF. At this time,counting is not possible forCP1 or CP2 inputs.OUT1, 2Note: The above is for when the output mode isK-2.
SUB mode can be used only whenK-2, D, L, or H is selected as the outputmode with 6-digit models.Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count value will be calculated based on a CP1present value of 0.2. Counting is not possible for CP2 during reset 2 input. CP1 will not be affected. The dual count value will be calculated based on a CP2present value of 0.3. The counting range for the dual count value is −99,999 to 999,999 (0 to 9,999 for 4-digit models).
The counting ranges for the CP1 presentvalue and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models). If a present value exceeds 999,999 (9,999 for 4-digit models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop.28Multifunction Preset Counter H7CX-A(Counter Function)Reset Function ListFunction1-stage/2-stagecounterScreen displayed in runmodePresent value/set value (1, 2)Total and preset counterPresent value/set valueBatch counterTotal countvaluePresent value/set valueDual counterBatch countDual countvalue/batchvalue/dualcount set value count set valuePresent value and output reset.CP1 presentvalue/CP2present valueReset/reset 1Present valuePresent value and output reset.and output reset.Only the CP1 present value is reset.Total reset/reset 2No effect.Reset keyCP1 present value, CP2 presentPresent valuePresent value,Present valuePresent valuePresent value,and output reset.
