1. System Configuration

If the Standard type expansion is used, all expansion interface modules must be the standard type. In this case, the maximum length of the expansion cable is 2m between units, 6m total.

If the long-distance type expansion is used, all expansion interface modules must be the long-distance type. In this case, the maximum length of the expansion cable is total 40m.

If the standard type expansion is used, the necessity of the power supply modules on the expansion units is determined depending on the internal current consumption. (See 1.9 Examining the power supply capacity)

The power supply mode plug of the expansion interface module must be set according to the power supply module mounting status.

If the long-distance type expansion is used, all expansion units should have the power supply modules.

The dedicated expansion cables are available for the standard expansion and for the long-distance expansion, respectively.

1.3 Power supply module

1. System Configuration

The following table shows that two types of power supply modules are available, depending on the power supply voltage. These modules can be used for both the basic unit and the expansion unit. The power supply module is mounted in the extreme left of the rack. However, the expansion rack that is connected to the standard expansion IF may not need the power supply module.

Battery cover:

A batteiy has been installed inside this cover at the factory shipment. The battery keeps the RAM contents (user program and user data) and supports the clock-calendar operation during power OFF.(See 5.4 Replacing battery)

RS232C port for the programmer :

The T-series programmer (T-PDS or HP911) is connected to the T3 through this port. Dedicated connection cables are available.

RS485 port for the computer link:

The CPU module has the computer link function as standard.

By using this function, T3 can communicate with a host computer or an intelligent equipment through RS485 interface. For details of the computer link function, see separate "T-series Computer Link Funciton Operation Manual".

IC memory card slot:

Optional !C memory card (type : ME914) is inserted into this slot. By installing the IC memory card, user program back-up/switchover or user data expansion become available. Refer to 5.6 IC memory card handling.

1.6 Expansion interface module

If the expansion units are used, the expansion interface modules must be mounted in each of the basic unit and the expansion units. There are basically two types of expansion interface modules-the standard type and the long-distance type. What type to use will depend on the cable distance. The dedicated expansion interface module must be mounted on each of the basic unit and the expansion units.

Expansion cable

Since there is no compatibility between the standard type and the long-distance type, these two types cannot be mixed in one T3 configuration.

The standard type expansion cable and the long-distance type expansion cable are not compatible with each other. (See Section 1.7 Expansion Cable.)

If the standard type is used, whether a power supply module is necessary for the expansion unit will depend on the internal 5 Vdc current consumption. (See Section 1.9 Examining the

power supply capacity.)

 

For the IF351, change the power supply

mode plug as shown in

the figure below (depending on whether

a power supply module

has been mounted on its own unit).

to 1-2 shorted (witii a power supply).

For the long-distance type, a power supply module is needed for each of the expansion units.

In the long-distance type, the IF312 is for basic unit, the IF352 is for middle expansion units and the IF353 is for the end expansion unit.

The following types of expansion cables are available.

For details on the specification of I/O modules, see 2.3, I/O module specifications.

Carefully read the Cautions described In Section 3 for applying I/O modules.

The I/O module can be mounted in any I/O slot functionally. However, to improve noise-immunity for the entire system, it is recommended to separate the low voltage 1/Os and the power I/Os. (See 4.7, I/O Wiring.)
