Explanation
• The priority of the LED indication in the case of an error is set
by a cause number. (For the Basic model QCPU, only the
annunciator (cause number 7) is available.)
• For the Universal model QCPU and LCPU, specify whether to
enable or disable LED indication of the error that has priority
when an error occurs.
• The setting areas for priorities are as follows:
b15 b12 b11 b8 b7
to to
SD207
Priority 4 Priority 3 Priority 2
SD208 Priority 8 Priority 7 Priority 6
SD209
Priority 12 Priority 11 Priority 10
(Priority 11 is valid when Redundant CPU is used.)
(Priority 12 is valid when LCPU is used.)
[Default value]
SD207 = 4321 (0000 for Basic model QCPU)

SD208 = 8765 (0700 for Basic model QCPU) (0765

H
• No indication if "0" is stored.
• For the Basic model QCPU, the ERR. LED lights up upon
turn-on of the annunciator, if "7" is stored in any of Priorities 1
to 11.
• For the Basic model QCPU, the ERR. LED does not light up
upon turn-on of the annumciator, if "7" is not stored in any of
Priorities 1 to 11.
However, even if "7" is stored, the error, which makes CPU
module operation stop (including the error that is specified
with a parameter), will be indicated with the LED without
condition.
