Alarm output
setting value
lower/lower limit
• Set the alarm output setting values (upper/upper limit,
upper/lower limit, lower/upper limit, lower/lower limit).
• The following setting values can also be set: upper/upper limit =
upper/lower limit, lower/upper limit = lower/lower limit. However,
an alarm output setting range outside error (error code: 500)
occurs if the setting value is outside the setting range or the
following relation expression is not established.
Upper/upper limit upper/lower limit lower/upper limit
lower/lower limit
To clear the error, turn ON the error reset request (Y8 to YF) of
the corresponding channel.
After this, set a correct value (value that will establish the above
relation expression and is within the setting range), and then turn
ON the operating condition setting request flag (Y1).

Count cycle
change function
selection
• Set whether the count cycle change function is valid or invalid.
• Set the count cycle in the "count cycle setting value" of the buffer
memory.
• By setting "count cycle change function selection valid", the
update timing of the "sampling pulse number" or "accumulating
count value" of the buffer memory becomes the time set in the
"count cycle setting value" of the buffer memory.
• When "count cycle change function selection invalid" is set, the
count cycle is fixed at 1s.
• If the setting value is other than 0 or 1, a count cycle setting
range outside error (error code: 600) occurs. To clear the error,
turn ON the error reset request (Y8 to YF) of the corresponding
channel. After this, set a correct value and then turn ON the
operating condition setting request flag (Y1).

Count cycle
setting value
• Set the count cycle of the "sampling pulse number" or
"accumulating count value" of the buffer memory.
• If the setting value is other than the following values, a count
cycle setting range outside error (error code: 600) occurs. To
clear the error, turn ON the error reset request (Y8 to YF) of the
corresponding channel. After this, set a value within the setting
range and then turn ON the operating condition setting request
flag (Y1).
