With quick-response inputs, signals that are changed within a scan canbe received by maintaining an internal buffer.SharedprocessingCalculationprocessingI/O refreshSharedprocessingCalculationprocessingI/O refreshInput terminal(00003)000031 scan3-153.FEATURES & FUNCTIONSInput number (See note.)00003000040000500006Minimum input signal width50 µsThe following table shows the relationships between interval timer interrupts and the CPM2A’sother functions.Synchronized pulse controlInterrupt inputsInterval timer interruptsHigh speed countersInterrupt inputs (counter mode)Pulse outputsQuick-response inputsInput time constantClockNote 1.2.3.4.•Interval time interruptsCan be used simultaneously.See note 1.Can be used simultaneously.Can be used simultaneously.See note 2.Can be used simultaneously.See note 3.See note 4.Can be used simultaneously.Quick response input utilize the interrupt input function, so the same input number from the00003 to 00006 cannot be assigned for both a quick response input and an interrupt input in thePLC setup.A quick-response input and an interrupt in counter mode cannot be assigned the same inputnumber in the PLC setup.The input numbers allocated for quick quick-response inputs are 00003 to 00006.
These inputscan be set and operated as quick-response inputs.Input time constants are disable for all inputs that are set as quick-response inputs.Marco FunctionThe macro function allows a single subroutine (programming pattern) to be used by simplychanging the I/O word. An number of similar program sections can be managed with just onesubroutine, thereby greatly reducing the number of steps in the program and making the programeasier to understand.To use a macro, call a subroutine by means of the MACRO instruction, MCRC(99), as shownbelow, instead of SBS (91) (SUBROUTINE ENTRY).MCRO(99)Subroutine NoFirst input wordFirst output word3-164.qUNIT SPECIFICATIONS AND COMPONENTSGeneral Specifications of CPM1A CPUs UnitItemSupply voltageOperating voltagerangePower consumptionInrush currentExternal powersupply (AC typeonly)AC typeDC typeAC typeDC typeAC typeDC typePower supplyvoltagePower supplyoutput capacityInsulation resistanceDielectric strengthNoise immunityVibration resistanceShock resistanceAmbient temperatureAmbient Humidity (operating)Ambient environment (operating)Terminal screw sizePower supply holding timeCPU weightNote :AC typeDC type10-point I/O20-point I/O100 to 240 VAC, 50/60 H24 VDC85 to 264 VAC20.4 to 26.4VDC30 VA max.6 W max.30 A max.24 VDC200 mA30-point I/O40-point I/O60 VA max.20 W max.60 A max.300 mA20 MΩ min.
