The following are details of the Q64RD I/O signals.
(1) Input signals
(1) If the module is in the normal mode at power-on or resetting of the PLC CPU, this signal turns
on to start temperature conversion processing as soon as it gets ready for temperature
conversion.
(2) When this signal (X0) is off in the normal mode, temperature conversion processing is not
performed. In the offset/gain setting mode, temperature conversion processing is performed if
this signal (X0) is off.
(3) This signal (X0) turns off when:
• The module is in the offset/gain setting mode;
• The Q64RD is in a watchdog timer error
(1) This signal is used as an interlock condition to turn on/off the CH.
