Outputs can be specified at the right ends oflines only. Inputs cannot be specified after outputs.3 inputs1st input2nd input1 output3rd inputOutput bitThe ladder program inputs and outputs are displayed on the ZENSupport Software screen as shown below.Ladder Diagram Display1st input2nd input3 inputs123rd inputOutput bit1 outputSection 2-1Circuit Diagrams and Ladder ProgramsElectrical Circuit Display1st input2nd input3rd inputOutput bit3 inputs1 outputNote On the ZEN Support Software displays bits in ZEN memory arecalled “relays,” program input bits are called “contacts,” and program output bits are called “coils.”2-1-3Memory AreasThe memory areas shown in the following table can be used in ZENladder programs.SymbolNameFunctionUsable as inputconditionUsable asoutputICPU Unit inputbitsCorrespond to CPU Unit inputterminals.YesNoXExpansion I/OUnit input bitsCorrespond to Expansion I/O Unitinput terminals.YesNoBButtonswitchesTurn ON/OFF when operationbuttons are pressed on the CPUUnit during ZEN operation.YesNoAAnalogcomparatorbitsYesPerform comparisons on a setvalue and the input values for CPUUnits with DC power supply inputs.(The analog input terminalscorrespond to I4 and I5 in 10-pointCPU Units, and to Ia and Ib in 20point CPU Units.)NoPTimer/countercomparatorbitsCompares timer/counter presentvalues and timer/counter presentvalues and settings.YesNo@Weekly timersTurns ON/OFF between specifieddays and times.YesNo∗CalendartimersTurns ON/OFF between specifieddates.YesNo13Section 2-1Circuit Diagrams and Ladder ProgramsSymbolQYNameFunctionUsable as inputconditionCan specifyCorrespond toCPU Unit output Normal output([), Set (S),terminals.Reset (R), orExpansion I/O Correspond toAlternate (A)Unit output bits Expansion I/Ooperation.Unit outputCPU Unitoutput bitsUsable asoutputYesYesYesYesterminals.MWork bitsBits that can beused in theladder program.YesYesHHolding bitsBits thatmaintain ON/OFF status atpowerinterruptionsand can be usedin the ladderprogram.YesYesTTimersTimers that can be used for ONdelay (X), OFF delay (■), Oneshotpulse (O), or Flashing pulse (F).YesYes#Holding timersTimers that maintain the presentvalue at power interruptions.

Select Create a new programand press the OK Button.If the ZEN Support Software has already been started, click theNew Button on the Toolbar.
Alternatively, select File/New fromthe Menu Bar.2.The Property Settings Screen will be displayed. Enter the ZENmodel, configuration (i.e., Expansion I/O Units), project name,and comment, and then click the OK Button.3.An empty screen in ladder-view format will be displayed. Doubleclick the mouse on the position for the first input condition.Note Input positions for input and output bits can be set by usingthe mouse or cursor keys to move to the input or output position and then 1) pressing the Enter Key, 2) double-clicking, 3) clicking the Insert Input or Insert Output Button onthe Toolbar, 4) selecting Insert-Contact/Coil from the16Section 2-2Inputting Ladder ProgramsMenu Bar, 5) selecting Edit/Edit from the Menu Bar, or 6)clicking the right mouse button and selecting Edit.4.The Edit Input Dialog Box will be displayed. Specify the bit type,type of input, and bit number, and enter a comment if required.Bit name: IInput: Normally openBit number: 0Comment: CPU Unit input bit 0(Up to 31 characters can beinput.)Comment colorNote a) Parameter settings are also specified for timers andcounters.b) Parameters are set on the Edit Input Dialog Box.5.Double-click the mouse on the next input position.17Section 2-2Inputting Ladder Programs6.The Edit Input Dialog Box will be displayed again.
