Details Of Input Signals - Mitsubishi Electric MELSEC iQ-R Series User Manual

Details of input signals

The following describes the details of the input signals for a temperature input module which are assigned to the CPU module.
The I/O numbers (X/Y) described in this section are for the case when the start I/O number of a temperature input module is
set to 0.
This section describes buffer memory addresses for CH1. For details on the buffer memory addresses after
CH2, refer to the following.
Page 99 Buffer Memory Areas
Module READY
Module READY (X0) turns on to indicate the preparation for the temperature conversion is completed after the power-on or
after the reset operation of the CPU module, and the temperature conversion is performed.
In the following cases, 'Module READY' (X0) turns off.
• In the offset/gain setting mode (In this case, the temperature conversion is performed.)
• When a watchdog timer error has occurred in the temperature input module (In this case, the temperature conversion is not
performed.)

Module READY
Operating condition setting completed flag
When changing values of the buffer memory, use Operating condition setting completed flag (X9) as an interlock condition to
turn on and off 'Operating condition setting request' (Y9). For the buffer memory areas which require turning on and off of
'Operating condition setting request' (Y9) to enable the changed values, refer to the following.
Page 99 Buffer Memory Areas
When 'Operating condition setting completed flag' (X9) is off, the temperature conversion is not performed.
When 'Operating condition setting request' (Y9) is on, 'Operating condition setting completed flag' (X9) turns off.
