function
Conversion completion The Conversion completion flag (XE) turns OFF when
flag (XE) disconnection is detected, and a value immediately
before the detection is held in the CH
temperature value (Un\G11 to 14, Un\G54 to 61).
The Conversion completion flag (XE) turns OFF when
disconnection is detected. Upon recovery of the
connection, the temperature conversion value update
is restarted independently of the Disconnection
detection signal (XC) reset. After the initial update, the
Conversion completion flag (XE) turns ON again.
Conversion completion When disconnection is detected, the Conversion
flag (Un\G10) completion flag (Un\G10) for the channel disconnected
turns OFF (0).
CH time/count/moving Setting options are "Time" and "Count" only. (see

The following shows differences between the Q64RD whose first 5 digits of product
information are 07071 or earlier and those of 07072 or later.
Q64RD
Digital output values sampled at specified number of
times are averaged.
By a preset time constant, digital output values are
smoothed.
For values to be stored in the CH
temperature value (buffer memory addresses 11 to 14,
54 to 61: Un\G11 to 14, Un\G54 to 61) in the case of
disconnection detection, any of "Value immediately
before disconnection", "Up scale (maximum value of
measured temperature range + 5% of measured
temperature range)", "Down scale (minimum value of
measured temperature range – 5% of measured
temperature range)" or "Given value" can be selected.
When disconnection is detected, the Conversion
completion flag (XE) does not turn OFF and a value
measured based on the Conversion setting for disconnection
detection (Un\G148) is stored in the CH
temperature value (Un\G11 to 14, Un\G54 to 61).
When disconnection is detected, the Conversion
completion flag (XE) does not turn OFF. Upon
recovery of the connection, the temperature conversion
value update is restarted independently of the
Disconnection detection signal (XC) reset.
When disconnection is detected, the Conversion
completion flag (Un\G10) for the channel disconnected
does not turn OFF (0).
There are four setting options: "Time", "Count", Moving
average" and "Time constant".
Use the Extended averaging processing specification
(Un\G134) to specify the averaging processing.
For values to be stored in the CH
temperature value (buffer memory addresses 11 to 14,
54 to 61: Un\G11 to 14, Un\G54 to 61) in the case of
disconnection detection, any of "Value immediately
before disconnection", "Up scale (maximum value of
measured temperature range + 5% of measured
temperature range)", "Down scale (minimum value of
measured temperature range – 5% of measured
temperature range)" or "Given value" can be selected.
