I/Os for external devices cannot be made(i.e., all I/O is internal).Holding bitsHH0 to Hf16Used the same as the work bits.

However, if thepower to the ZEN is turned OFF, these bits alsomaintain the previous ON/OFF status.TimersTT0 to Tf16X: ON-delaytimer: (box) OFFdelay timerO: One-shotpulse timerF: Flashingpulse timerFunctions areselected fromthe screenwhen parameter settings aremade.Time units canbe selectedfrom the following: 0.01-s unit:0.01 to 99.99 smin/s unit: 00min 01 s to 99min 59 s h/sunit: 00 h 01min to 99 h 59min-12Holding timers##0 to #78Hold the present value being counted even if thetrigger input or power supply is turned OFF andcontinue timing when the trigger input or power isrestored.CountersCC0 to Cf16Reversible counters that can be incremented anddecremented.3Weekly timers@@0 to @f16Turn ON and OFF during specified times onspecified days.4Calendar timers**0 to *f16Turn ON and OFF between specified dates.5Display bitsDD0 to Df16Display any character string, time, or analog-converted display of timer or counter present values.6Analog compara- Ator bitsA0 to A34Used as program input conditions to output analog comparator comparison results.

These bitscan be used only for 24-VDC input CPU Units.7Timer/countercomparator bitsPP0 to PfCompare the present values of timers (T), holding timers (#), and counters (C). Comparison canbe made between the same two counters or timers, or with constants.8Button input bitsBUsed as program input conditions and turn ONwhen operation keys are pressed in RUN Mode.These input bits can be used only with LCD-typeCPU Units.9B0 to B7168Note: * CPU Units with 10 I/O points have 6 input bits (I= to I5) and 4 output bits (Q0 to Q3).2More detail information on the coming pagesProgrammable Relay ZEN71 Additional Bit Output Functions[: NormalS: SetI0R: ResetI1A: AlternateI2[ Q0I3SQ 1RQ 1AQ 2I0I1I2I3Q0Q1Q1Q2Q0 will turn ON or OFF depending Q1 will stay ON once the execution Q1 is forced OFF when theon the ON/OFF status of thecondition I1 has turned ON once.
