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

peripheral or RS-422/485 port.
OFF Data isn't being transferred via
communications port.
COMM2
(yellow)
Flashing Data is being transferred via the
RS-232C port
OFF Data isn't being transferred via
communications port.
