Note

! Caution

Include the CompoBus/S communications data high/low terminal, commu- nications power supply +/– terminals, and NC terminals. Power is supplied to the Unit internally, so the power supply terminals can be used as relay terminals.

2.DIP Switch

The DIP switch sets the Unit’s node address, sets the communications mode, and determines whether or not the outputs will be cleared in the event of a communications error.

Pin(s)

DR

ON: Long-distance Communications Mode

 

 

OFF: High-speed Communications Mode

 

 

(See note.)

 

 

 

 

 

HOLD

ON: Retain outputs when a communications error occurs.

 

OFF: Clear outputs when a communications error occurs.

The Long-distance Communications Mode can be used only when connected to one of the following Master Units: C200HW-SRM21-V1, CQM1-SRM21-V1, or SRM1-C0j-V2.

3.LED Indicators

These indicators show the status of CompoBus/S communications.

Indicator

Status

Meaning

 

 

 

COMM

ON

Communications in progress.

(yellow)

 

 

OFF

Communications error or stopped.

 

 

 

 

ERR

ON

A communications error has occurred.

(red)

 

 

OFF

Indicates normal or no communications.

 

 

 

 

4.Expansion I/O Unit Connecting Cable

Connects the CompoBus/S I/O Link Unit to the Expansion Connector on the PC’s CPU Unit or another Expansion Unit.

Do not touch the Expansion I/O Unit Connecting Cable while the power is being supplied in order to prevent any malfunction due to static electricity.

5. Expansion Connector

Connects to another Expansion Unit (Expansion I/O Unit, Analog I/O Unit, or CompoBus/S I/O Link Unit). Up to 3 Expansion Units can be connected to a CPU Unit.
