1. DIP switch

•RS-232C and peripheral port settings

					Pin 1	Effective port settings
					OFF	The ports operate according to the settings in the
					(default)	PLC setup.
						RS-232C port settings: DM 6645 to DM 6649
	ON
						Peripheral port settings: DM 6650 to DM 6654
					ON	The ports operate with the standard communications
1		2	3	4		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.

Programming device	Startup mode with	Startup mode with
connected	Pin 2 OFF (default)	Pin 2 ON
None	RUN mode	PROGRAM mode
Programming console	Operating mode set on the programming console's
	mode switch
Other device	PROGRAM mode

2. Input indicators (yellow)

IN0	OUT0	The input indicators are lit when the corresponding
IN1	OUT1	input terminal is ON. The status of an input indicator
IN2	OUT2	will reflect the status of the input even when that input
IN3	OUT3	is being used for a high-speed counter.
IN4
IN5

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)

	A	The indicators are lit when the corresponding input
	B	terminal is ON.
	Z
5. PLC status indicators

The following indicators show the operating status of the PLC.

	Indicator	Status	Meaning
PWR	PWR	ON	Power is being supplied to the unit
	(green)
RUN		OFF	Power isn't being supplied to the unit
ERR/ALM	RUN	ON	The PLC is operating in RUN or
COMM1	(green)		MONITOR mode
COMM2
		OFF	The PLC is in PROGRAM mode or
			a fatal error has occurred.
	ERR/ALM	ON	A fatal error has occurred.
	(red)		(PLC operation stops.)
		Flashing	A non-fatal error has occurred.
			(PLC operation continues.)
		OFF	Indicates normal operation.
	COMM1	Flashing	Data is being transferred via the
	(yellow)		peripheral or RS-422/485 port.
		OFF	Data isn't being transferred via
			communications port.
	COMM2	Flashing	Data is being transferred via the
	(yellow)		RS-232C port
		OFF	Data isn't being transferred via
			communications port.
