Caution341. When using OUT01000 or OUT01001 as a pulse output, connect a dummyresistor as required to bring the load current between 0.01 and 0.1 A. If theload current is below 0.1 A, the ON-to-OFF response time will be shorter andhigh-speed pulses (source-type transistor outputs) will not be output. If theload current is above 0.1 A, the transistor will generate more heat and components may be damaged.2. The total for OUT01000 to OUT 01003 must be 0.8 A maximum.
If the ambient temperature is maintained below 50 °C, however, up to 0.9 A/commoncan be used.Do not apply voltage in excess of the maximum switching capacity to an outputterminal.

PC Status IndicatorsThese indicators show the operating status of the PC, as shown in the following table.IndicatorPWR(green)RUN(green)COMM(yellow)StatusONOFFONOFFFlashingOFFERR/ALARM(red)ONFlashingOFFMeaningPower is being supplied to the PC.Power isn’t being supplied to the PC.The PC is operating in RUN or MONITOR mode.The PC is in PROGRAM mode or a fatal error hasoccurred.Data is being transferred via the Peripheral port orRS-232C port.Data isn’t being transferred via the Peripheral portor RS-232C port.A fatal error has occurred. (PC operation stops.)A non-fatal error has occurred.
(PC operationcontinues.)Indicates normal operation.8. Input IndicatorsThe input indicators are lit when the corresponding input terminal is ON. Theindicators are lit during I/O refreshing.When a fatal error occurs, the input indicators change as follows:Fatal errorCPU Unit error, I/O bus error,or too many I/O UnitsMemory error or FALS (fatalsystem) errorInput indicatorsTurn OFF.The indicators will change with the status ofthe input signal, but input status will not beupdated in memory.Note a) When interrupt inputs are used in interrupt input mode, the indicator may not light even when the interrupt condition is met if the input is not ON long enough.b) When high-speed counters are used, the input indicator may notlight if the input pulse is too fast.9. Output IndicatorsThe output indicators are lit when the corresponding output terminal is ON.The indicators are lit during I/O refreshing. When pulse outputs are beingused, the indicator will remain lit continuously while the pulses are being output.36Unit ComponentsSection 2-210.
