5 FUNCTIONS (3) When comparing with 17 points or more of the continuous comparison point setting For the QD64D2, settable continuous comparison No.1 point n setting (Un\G54 to 85) is up to 16 points each. Therefore, when comparing with 17 points or more, execute the following procedures. (a) Initial setting Set the following and turn from OFF to ON the continuous comparison No.1 execution command (Y09). • Continuous comparison No.1 start point setting (Un\G50) = 1 *1 • Continuous comparison No.

5 FUNCTIONS 5.3.3 Using the coincidence output test function Use the coincidence output test function to check the wiring of the coincidence output No.1 terminal (EQU1) and the coincidence output No.2 terminal (EQU2) when selecting the continuous comparison function. When using the continuous comparison function, the coincidence output No.1 terminal (EQU1) and the coincidence output No.2 terminal (EQU2) automatically turn OFF. Therefore, check the wiring using the coincidence output test function.
FUNCTIONS • Even if the coincidence output No.1 test command (Y0B) and the coincidence output No.2 test command (Y0C) are turned ON, the counter value coincidence No.1 (X02) and the counter value coincidence No.2 (X05) do not turn ON/OFF. (Coincidence detection interrupt also does not occur.) • The coincidence output test function cannot be used when selecting the coincidence output function.
5 FUNCTIONS 5.3.4 Coincidence detection interrupt function Use the coincidence detection interrupt function to request an interrupt to the programmable controller CPU when a coincidence is detected, and start up the interrupt program. (a) Up to 16-point interrupt factors (SI) are allowed for a single MELSEC-Q series intelligent function module. As shown in Table 5.9, the QD64D2 has 4-point interrupt factors (SI) for coincidence detection. Table 5.9 List of interrupt factors SI No.

5 FUNCTIONS POINT • Coincidence detection interrupt occurs at the rising edge (OFF ON) of the counter value coincidence No.1 (X02) or the counter value coincidence No.2 (X05). Therefore, next interrupt request does not occur unless the counter value coincidence No.1 (X02) and the counter value coincidence No.2 (X05) are reset and turned OFF. • When using the coincidence output function, the counter value coincidence No.1 (X02) and the counter value coincidence No.

1 Using the Latch Counter Function The latch counter function latches the present value (Un\G12 and 13) to the latch count value (Un\G14 and 15). The following two methods are available for latch operation. • Turn ON the latch counter execution command (Y07) by the sequence program. • Turn ON the latch counter input terminal (LATCH) of external input. In (1) below, I/O numbers (X/Y) and buffer memory addresses are listed for channel 1.
5 FUNCTIONS Table 5.12 Details of operation example of the latch counter function Number Description When the latch counter execution command (Y07) is turned from OFF to ON, 1) the present value (Un\G12 and 13) is stored in the latch count value (Un\G14 and 15). When the latch counter input terminal (LATCH) is turned from OFF to ON, the 2) 3) 4) 5 - 30 present value (Un\G12 and 13) is stored in the latch count value (Un\G14 and 15).
1 (b) Control cycle (1ms) of the QD64D2 Up to 2ms (1 control cycle 2) of delay occurs until the QD64D2 reads out the output signal and buffer memory updated by the sequence program and completes processing. Update timing of the I/O signal and buffer memory varies within the range of a control cycle.
