CPU unit component descriptions

1. DIP switch

•RS-232C and peripheral port settings

•Operating mode at startup

Pin 2 determines the operating mode at startup only if there isn't a

programming device connected to the peripheral port.

2. Input indicators (yellow)

The input indicators are lit when the corresponding

input terminal is ON. The status of an input indicator

will reflect the status of the input even when that input

is being used for a high-speed counter.

Note:1. When interrupt inputs are used in interrupt input mode, the in-

dicator may not light even when the interrupt condition is met

if the input is not ON long enough.

2. Input indicators will reflect the status of the corresponding in-

puts even when the PLC is stopped, but the corresponding in-

put bits will not be refreshed.

3. Output indicators (yellow)

The output indicators are lit when the corresponding output terminal is

ON. The indicators are lit during I/O refreshing. The status of an output

indicator will also reflect the status of the corresponding output when

the output is being used as a pulse output.

4. High-speed counter indicators (yellow)

The indicators are lit when the corresponding input

terminal is ON.

5. PLC status indicators

The following indicators show the operating status of the PLC.

Indicator Status Meaning

PWR

(green) ON Power is being supplied to the unit

OFF Power isn't being supplied to the unit

RUN

(green) ON The PLC is operating in RUN or

MONITOR mode

OFF The PLC is in PROGRAM mode or

a fatal error has occurred.

ERR/ALM

(red) ON A fatal error has occurred.

(PLC operation stops.)

Flashing A non-fatal error has occurred.

(PLC operation continues.)

OFF Indicates normal operation.

COMM1

(yellow) Flashing Data is being transferred via the

peripheral or RS-422/485 port.

OFF Data isn't being transferred via

communications port.
