MELSEC-Q
5 BASIC USAGE
(2) Output status setting during a CPU stop error
The output status (clear/hold) can be set for the external output signal when a
CPU stop error occurs.
The output status is set using the GX Developer I/O assignment.
See Section 4.5 for details on the I/O assignment setting method.
(3) Coincidence detection interrupt function
The coincidence detection interrupt function allows making an interrupt request to
a CPU module at the time of coincidence detection to start the interrupt program.
(When the CPU module is a Q00J/Q00/Q01CPU, use function version B or later.)
(a) With the MELSEC-Q series intelligent function module, each module can
have up to 16 points of interruption factors (SI).
The QD62 (E/D) has 4 points of interrupt factors corresponding to the
coincidence outputs shown below.
SI No. Interruption factor
0 Channel 1: Coincidence detection for coincidence output point No. 1
1 Channel 1: Coincidence detection for coincidence output point No. 2
2 Channel 2: Coincidence detection for coincidence output point No. 1
3 Channel 2: Coincidence detection for coincidence output point No. 2

(b) Select "PLC parameter" - "PLC system" - "Intelligent function module setting"
- "Interrupt pointer settings" to set the interrupt factors (SI) of the QD62(E/D)
and interrupt pointers of the CPU module.
1) CPU side [Interrupt pointer start No.]
Set the start interrupt pointer number of the CPU module.
Setting range: 50 to 255
2) PLC side "Interrupt pointer No. of module"
Set the number of interrupt factors (SI).
Setting range: 1 to 4
