Output State Control
Can select the method to control the output
states when the CPU operation mode is
changed or when an error occurs.
• Continue updating output states automati-
cally.
• Hold the output states.
• Bring the pre-defined output state.

The pulse rate measurement function cannot
be used.

Same as at the left. However, because the NJ
Series has no power OFF interrupt task, opera-
tion cannot be restarted from the position at
which the power was interrupted.
The IORD/IOWR instruction cannot be used.
Therefore, you cannot read or write the data on
