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.

1. CD332 Overview Status LEDs Indicates the input signal ON/OFF status (DATA 0 - 7) and the interrupt generation point (STATUS 0 - 7). Normally STATUS 0 - 7 are all OFF. (momentary ON) DATA 0 - 7 STATUS 0 - 7 Indicates the input signal status of IN0 to IN7. Lit when ON. Indicates the input point which is the interrupt factor. (returned to OFF by resetting the interrupt flag) Interrupt timing setting DIP switches Total 16 switches are provided.

Section 3 Mode Setting 3.1 Input delay setting, 14 3.
3. Mode Setting 3.1 Input delay setting The input delay time of the CD332 can be selected either normal or high speed mode. Refer to section 2.2 for the delay time of each mode. The input delay setting is made by the jumper plugs provided on the CD332’s printed circuit board. This setting is applied for all 8 input points as a block. CD332 left side J9 A B A J10 B J11 J1 J2 J3 J4 J5 J6 J7 J8 Set these jumper plugs as follows.
3. Mode Setting 3.2 Interrupt generation timing setting The interrupt generation timing of each input point can be selected either rising, falling or both edges. • Rising edge (OFF to ON) Input OFF ON OFF ON OFF Interrupt • Falling edge (ON to OFF) Input OFF Interrupt • Both edges (OFF to ON and ON to OFF) Input OFF ON OFF Interrupt This setting is made by the DIP switches provided on the front of the CD332.

Section 4 I/O Allocation 4.1 I/O allocation and I/O register, 18 4.
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.
4. I/O Allocation The following table shows the function of each bit of the input register assigned to 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.
Section 5 Programming 5.1 T3 sample program, 22 5.
5. Programming 5.1 T3 sample program The following sample program configuration shows the case of one CD332 is used. In this example, it is assumed that XW000 is assigned to the CD332.
5. Programming c At the first scan, initializes the status of the CD332. − Important d End of the main program e Resets the interrupt flag and confirms the interrupt factor. − Important f Processing program for each interrupt factor (Subroutine call can also be used) g End of the interrupt program NOTE When the Direct I/O instruction for the CD332 is executed, the internal interrupt flag of the CD332 is reset.
5. Programming 5.2 Interrupt operation The enable/disable of the interrupt program is changed as follows. PLC mode HALT Scan Interrupt RUN 1 HOLD RUN 2 Disable n Enable Disable (Hold) HALT n+1 Enable Disable Time In the RUN mode, interrupt operation is disabled at the first scan, and enabled from the second scan. In the HALT mode, interrupt operation is disabled. In the HOLD mode, interrupt operation is disabled but the interrupt requests occurred during HOLD mode is held.
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).
