Interruption Due To Error Detection; Led Indication Due To An Error - Mitsubishi Q2ACPU User Manual

9. MAINTENANCE FUNCTION
9.3.1

Interruption due to error detection

QnACPU can execute the interrupt program, which is interrupt pointer I32 to I39, at error
occurrence.
In the case of errors for which operation can be set to continue or stop in PC RAS setting
in the GPP function parameter mode, this function is only executed when "Resume" is set.
If "Pause" is set for the error, a stop error interrupt program (I32) is executed.
The following shows the relevant errors.

LED indication due to an error

In the case of an error occurrence, the LED/LED indicator on the front face of the CPU
module gives a visual indication.For details on the operation of the LED, refer to Section
9.9.

POINT
Interrupt pointers I32 to I39 are prohibited for execution when the PLC power is
ON or when the CPU module is reset.
To use I32 to I39, make the execution allowed with IMASK instruction.
1) For details on interrupt pointers, refer to the QnACPU Programming Manual
(Fundamentals).
2) For the IMASK instruction, refer to the QCPU (Q mode)/QnACPU
Programming Manual (Common Instructions).
Errors for which the operation mode at the
occurrence of the error is "Resume", or for
which "Resume" is set if it is possible to select
"Pause/Resume"
