System Configuration

Section 1-2

 

 

 

There are three models of Expansion Units available: the Analog I/O Unit, Com- poBus/S I/O Link Unit, and Temperature Sensor Units.

Expansion Connector

Expansion I/O Unit, Analog I/O Unit, CompoBus/S I/O Link Unit, or Tem- perature Sensor Unit)

Expansion I/O Connecting Cable

A PC with 100 I/O points (the maximum) can be assembled by connecting three

Expansion I/O Units.

3 Units = 60 inputs, 40 outputs

(24 inputs, 16 outputs)

(12 inputs, 8 outputs)

A PC with 6 analog inputs and 3 analog outputs (the maximum) can be as- sembled by connecting three Analog I/O Units.

A PC with up to 6 temperature inputs for input from thermocouples or platinum resistance thermometers can be assembled by connecting Temperature Sensor Units.

CompoBus/S I/O Link Units (Slave Units) can be connected to a CPU Unit. I/O data (8 inputs and 8 outputs) is transferred between the CPU Unit and the area allocated to the CompoBus/S Slave. (The I/O data exchanged with the Slave is internal data; there are no external input or output terminals.)

Note Different types of Expansion Units can be connected at the same time. For ex- ample, an Expansion I/O Unit, Analog I/O Unit, and CompoBus/S I/O Link Unit, or an Expansion I/O Unit, Analog I/O Unit, and Temperature Sensor Unit can be connected to the CPU Unit.
