Continues the timing when the trigger inputor power supply is turned ON again.55CounterC0 to 78Reversible counters that can beincremented and decremented.58Weeklytimer@0 to 78Can turn ON or OFF during a specified day or time period.600 to 78Can turn ON or OFF during a specified date period.62Calendar timerNoteFunctionUse in ladder programsPageTimers can switch between operations. Refer to page 46.X ON delay Times down while the trigger input is ON and turns ON the timer bit when the settime is reached.■ OFFdelayTurns ON the timer bit while the trigger input is ON, starts timing down when thetrigger input turns OFF, and turns OFF the timer bit when the set time is reached.O One-shot Turns ON the timer bit for the set period when the trigger input changes from OFFto ON only.F FlashingpulseTimer bit repeatedly turns ON/OFF at set intervals while the trigger input is ON.Display BitsNameDisplayTypeBitaddressesD0 to 7No.ofbitsFunctionUse in ladder programsOutputDisplay user-set characterstrings, times, timer present values, counter present values, oranalog-converted values.8Function switchingDDisplay No.Function switching26DDisplayCClear display- - - (Ver.

Refer to page 30.DIN TrackConnect Power Supply, Input, and OutputDevicesWire the ZEN to the power supply, input, andoutput devices. Refer to page 31.PowersupplyWrite ProgramInput the ladder program, includingtimers, counters, and other parameters.Use the ZEN Support Software whenusing the LED-type CPU Units (withoutLCD or operation buttons.) Refer topage 40.OperationbuttonsONPerform trial operation before starting actualoperation and check that the system isoperating correctly.
