The following are details of the Q64RD/Q64RD-G I/O signals.
(1) Input signals
(1) If the module is in the normal mode at power-on or resetting of the programmable controller
CPU, this signal turns on to start temperature conversion as soon as it gets ready.
(2) When this signal (X0) is off in the normal mode, temperature conversion is not performed. In the
offset/gain setting mode, temperature conversion is performed even if this signal (X0) is off.
(3) This signal (X0) turns off when:
• The module is in the offset/gain setting mode;
• The Q64RD/Q64RD-G is in a watchdog timer error
(1) This signal is used as an interlock condition to turn on/off the CH
Y3, Y5, Y7)/CH
(2) When the CH
Y4, Y6, Y8) is turned from ON to OFF in the offset/gain setting mode, this signal (X1 to 4)
corresponding to the user-set, conversion-enabled channel turns on.

(Y2, Y4, Y6, Y8)
(1) This signal is used as an interlock condition to turn on/off the Operating Condition Setting
Request (Y9) when the "Conversion enable/disable setting", "CH
average/time constant setting (Q64RD-G)", "averaging processing specification" , "Extended
averaging processing specification", "Warning output enable/disable setting", "CH
range upper/lower limit value", "CH
output upper/lower limit value", "Conversion setting for disconnection detection" or "CH
Conversion setting value for disconnection detection" is changed.
(2) Conversion processing is not performed when this signal (X9) is off.
(3) This signal (X9) turns off when:
• The Module Ready (X0) is off in the normal mode; or
• The Operating Condition Setting Request (Y9) is on.

(4) The Q64RD-G clears measured temperature values immediately after Operating Condition
Setting Request (Y9) turned ON. Therefore, before reading measured temperature values,
confirm that Conversion Completion Flag (XE) has turned ON. The Q64RD holds measured
temperature values immediately after Operating Condition Setting Request (Y9) turned ON.
1 Occurs if program operation is not completed within the intended time due to a
hardware fault of the Q64RD/Q64RD-G. The RUN LED of the Q64RD/Q64RD-G
goes off when a watchdog timer error occurs.
