Connecting to a CPU	￿
	C-series C￿￿H, CVM1/CV-series (-EV￿)

Reference Only CVM1/CV series CPU units designated “-EV1” or higher can be connected.

Set the operating conditions with the PC System Setting functions when a C H, CVM1/CV-series host link unit is connected to the NT600S. The PC sys-

tem settings can be made directly from the peripheral tool (LSS etc.) or the PC system setting information created with a peripheral tool can be transferred to the CPU.

The following describes the switch settings so as to enable the PC system set- tings. For the details of the PC system settings, refer to the “SYSMAC C￿￿H User’s Manual (Programming)” (W176-E1-￿) and the “SYSMAC CVM/CV-Se- ries Support Software Operation Manual (Details)” (W196-E1-￿).

(1) C-series C￿￿H : C20H/C28H/C40H/C60H

No switch settings are required when connecting to a C-series C￿￿H CPU.

(2) CVM1/CV-series : CV500-CPU01-EV1

CV1000-CPU01-EV1

CV2000-CPU01-EV1

CVM1-CPU01-EV1

CVM1-CPU11-EV1

CVM1-CPU11-EV2

CVM1-CPU21-EV1

I/O port selector switch RS-232C

RS-422A

Only CVM1/CV series CPU units designated “-EV1” or higher can be con- nected.

When connecting to a CVM1/CV-series CPU, set the switches as given be- low.

[Setting the front￿switches]

￿I/O port selection (selector switch) Set this to “RS-232C”.

System setting (DIP SW4)

To effect the existing DIP switch settings, set SW4 to “ON”. To effect the existing PC system settings, set SW4 to “OFF”. Note: In the case of CPU units manufactured before June

1995 (lot No. “￿￿65”), the factory settings of the DIP switches do not agree with the factory settings for the PC system settings.

The factory settings for the DIP switches are: ￿2400 bps, 1 stop bit, even parity, 7-bits data length.

The factory settings for the PC system settings are: 9600 bps, 2 stop bits, even parity, 7-bits data length.

For CPU units manufactured from July 1995 (lot No. “￿￿75”) onward, the factory settings for the DIP switches are also 9600 bps and 2 stop bits.
