1. T3H Overview

1.1 Introducing the T3H

The T3H is a high performance large scale programmable controller.

Program memory capacity:

The T3H is available in two CPU types, PU325H and PU326H. Each type has the following user program memory capacity.

PU325H: 32 k steps

PU326H: 64 k steps

I/O points:

The T3H can handle up to 76 I/O modules in its local configuration. And the T3H has 512 words of external I/O register (data memory).

If all the I/O modules are discrete I/Os, the T3H can control up to 4864 points.

(64 points ⋅ 76 = 4864 points)

If all the I/O modules are analog I/Os, the T3H can control up to 512 channels of analog signals.

High speed processing:

A standard 16-bit micro processor and a special designed language processor are used in the T3H CPU. This dual-processor architecture provides high speed processing.

0.09	∝ s/contact	0.18	∝ s/coil
0.54	∝ s/16-bit transfer	0.90	∝ s/16-bit addition

Multitasking:

The T3H supports the multitask processing. By using this function, suitable control interval for a target application can be obtained.

1 ⋅ internal timer interrupt (interval setting: 1 to 1000 ms, 1 ms units)

8 ⋅ I/O interrupts (activated by external events)

1 ⋅ main program (core of the user program)

4 ⋅ sub-programs (activated from other tasks and executed as back-ground job)

Multiple programming languages:

The T3H supports two types of programming languages, i.e. ladder diagram and SFC (Sequential Function Chart). The ladder diagram is suited for logic control, and the SFC is suited for sequential control. These languages can be used in mixture.

High performance software:

The T3H supports 24 basic ladder instructions and 204 function instructions. Floating points data processing is also available. The T3H can be applied to complex control applications.

Network support:

The T3H can be connected to work-stations/personal-computers through Ethernet. Peer-to-peer communications between two T3H’s via Ethernet is also available. For high-speed control-data linkage, TOSLINE-S20/F10 can be used.
