CPU Unit Component Descriptions

1, 2, 3... 1. Power Supply Input Terminals

Connect the power supply (100 to 240 VAC or 24 VDC) to these terminals.

2.Functional Earth Terminal ( )

Be sure to ground this terminal (AC-type PCs only) to enhance immunity to noise and reduce the risk of electric shock.

3.Protective Earth Terminal ( )

Be sure to ground this terminal to reduce the risk of electric shock.

4.Power Supply Output Terminals

CPM1A PCs are equipped with these 24-VDC power output terminals to supply power to input devices. (AC-type PCs only.)

5.Input Terminals

Connect the Unit to external input devices.

6.Output Terminals

Connect the Unit to external output devices.

7.PC Status Indicators

These indicators show the operating status of the PC, as shown in the fol- lowing table.

	Indicator	Status	Meaning

	PWR (green)	ON	Power is being supplied to the PC.

		OFF	Power isn’t being supplied to the PC.

	RUN (green)	ON	The PC is operating in RUN or MONITOR mode.

		OFF	The PC is in PROGRAM mode or a fatal error
			has occurred.
	ERR/ALARM	ON	A fatal error has occurred. (PC operation stops.)
	(red)
	(red)	Flashing	A non-fatal error has occurred. (PC operation
		Flashing	A non-fatal error has occurred. (PC operation
			continues.)

		OFF	Indicates normal operation.

	COMM (orange)	ON	Data is being transferred via the Peripheral Port.

		OFF	Data isn’t being transferred via the Peripheral
			Port.

8.Input Indicators

These indicators are lit when the corresponding input terminal is ON. When a fatal error occurs, the input indicators change as follows:

Fatal error	Input indicators

CPU Unit error or I/O bus error	Turn OFF.

Memory error, no END instruction	The indicators will change with the
error, or system error	status of the input signal, but input
	status will not be updated in memory.

9.Output Indicators

These indicators are lit when the corresponding output terminal is ON.

10.Analog Controls

Setting these controls sets the contents of IR 250 and IR 251 from 0 to 200.

11.Peripheral Port

Connects the PC to a Peripheral Device, RS-232C Adapter, or RS-422 Adapter.

12.Expansion I/O Unit Connector

Connects the PC’s CPU Unit to an Expansion I/O Unit to add another 12 input points and 8 output points. Up to 3 Expansion I/O Units can be con- nected.
