WARNING  
CAUTION  
Indicates a potentially hazardous situation which, if not avoided,  
may result in minor or moderate injury. It may also be used to alert  
against unsafe practices.  
Safety Precautions  
!
CAUTION  
Turn off power to the T3 and to the CD332 before removing or mounting the CD332.  
Failure to do so can cause electrical shock or damage to this product.  
Read the Safety Precautions described in the T3 User’s Manual before using the T3  
and the CD332.  
Follow the instructions described in this manual and in the T3 User’s Manual when  
installing and wiring the T3 and the CD332.  
The CD332 has been designed for the T3. Use your CD332 only on the rack of the T3.  
Remove the CD332 from the rack before setting the jumper plugs on the CD332.  
Do not touch other components on the CD332’s printed circuit board. It may cause  
damage to the CD332.  
The CD332 consumes maximum 0.3 A of internal 5 Vdc power. Confirm that the total  
5 Vdc consumed current per one power supply module is within the limit (7A).  
If it exceeds the limit, the T3 cannot operate properly and this may cause unsafe  
situation.

1. CD332 Overview  
1.1 Introduction  
The change detect DC input module CD332 (hereafter called CD332) is an 8 points 12  
- 24 Vdc input module with interrupt generation function for Toshiba’s Programmable  
Controller PROSEC-T3 or T3H (hereafter called T3 generically).  
When the input signal status of the CD332 is changed, the CD332 generates an  
interrupt for the T3. Then the T3 immediately stops ordinary operation and starts to  
execute the pre-assigned I/O interrupt program.  
The task switching time in the T3 is less than 500 µs. (under interrupt enable state)  
The interrupt generation timing of the CD332 can be selected as follows for each input  
point. This selection is made by the DIP switches provided on the front of the CD332.  
(1) Rising edge (from OFF to ON)  
(2) Falling edge (from ON to OFF)  
(3) Both edges (both OFF to ON and ON to OFF)  
This CD332 has 8 input points. By using one CD332, up to 8 interrupt factors can be  
processed. On the other hand, up to 8 I/O interrupt programs are available in the T3.  
Therefore, total up to 64 (= 8 × 8) interrupt factors can be processed by the T3 by using  
8 CD332s.  
The input voltage of the CD332 is 12 to 24 Vdc. The input delay time can be selected  
either normal or high speed as 8 points block by setting the internal jumper plugs.  
NOTE  
The T3 supports 8 I/O interrupt programs. Therefore, maximum 8 CD332s  
can be used with the T3.

4. I/O Allocation  
4.1 I/O allocation and I/O register  
The CD332 has the I/O type ‘i X 1W’ for I/O allocation. When the automatic I/O  
allocation is performed with mounting the CD332, the following I/O allocation table will  
be created in the T3.  
(T-PDS screen example - in the case that CD332 is mounted on Slot 0 of Unit 0)  
Then, one input register, XW(n) is assigned to the CD332.  
In the above example, XW000 is assigned.  
Note that the I/O type has ‘i’ designation. It means that the CD332 has interrupt  
generation function for the T3, also the T3 will not update the assigned input register in  
the batch I/O processing. To read data through the input register, the Direct I/O  
instruction (FUN235) is necessary.

The data of the CD332 can be read into the XW(n) register by using the Direct I/O  
instruction (FUN235).  
By executing the Direct I/O instruction, the interrupt flag (interrupt request) is reset to  
OFF internally, and at the same time, the status bits are reset to OFF inside the CD332.

4. I/O Allocation  
4.2 Interrupt assignment  
The T3 has 8 I/O interrupt programs, I/O#1 to I/O#8.  
If one interrupt generation module (CD332) is used, the I/O#1 program is assigned to  
the CD332. And the I/O#1 is activated when the CD332 generates an interrupt.  
If two or more (up to 8) interrupt generation modules (CD332, etc.) are used, the  
interrupt programs are assigned sequentially from the module allocated closest to the  
T3 CPU.  
For example, if 3 CD332s are used, the I/O#1, I/O#2 and I/O#3 are assigned  
sequentially as follows.

As for the interrupt priority, the interrupt generation module which is allocated closest to  
the T3 CPU has highest priority and followed by this order.  
NOTE  
In default, the T3’s I/O interrupt program and the interrupt generation module  
are related as mentioned above. However user can change this relation  
(assignment) by using the interrupt assignment function of the T3.  
For this function, refer to the T3 User’s Manual - Function.

5. Programming  
The interrupt operation can be controlled by the user program instructions, DI (disable  
interrupt) and EI (enable interrupt). If a part of program is required to be executed under  
interrupt disable state, these instructions can be used.  
When using these instructions, note the following precautions.  
On the T3 program, interrupt enable/disable can be controlled by using EI instruction  
(FUN140) and DI instruction (FUN141). These instructions should be used in a pair  
in the sequence of DI first and followed by EI.  
(Main program)  
A
[ DI ]  
Interrupt is disabled  
(interrupt signal is held)  
A
[ EI ]  
EI and DI instructions should not be used in interrupt program. Also, these  
instructions should not be executed in the first scan.  
When using the interrupt function, the following general precautions should be  
considered.  
The high frequency of the interrupt generation will cause T3 inoperative. Because, in  
such case, the T3 becomes busy to execute the interrupt program, and cannot  
execute the main program.  
When the CD332 is used, pay attention to the external noise environment.  
Especially, when using the high speed response mode, check this point carefully.
