PROSEC 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.

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

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.
