Default setting registration command
Turning from OFF to ON 'Default setting registration command' (Y9) returns the data in the buffer memory to the default
values according to the control output cycle unit selection setting and the control mode setting. After the data writing is
completed, 'Default value write completion flag' (X9) turns ON. ( Page 167 List of buffer memory addresses)
■When 'Setting/operation mode status' (X1) is ON (in the operation mode)
Turning from OFF to ON this command does not set back the data to the default values. Turn ON this command when
'Setting/operation mode status' (X1) is OFF (in the setting mode).
■Reflection of set values
Usually, when the settings in the buffer memory have been changed, 'Setting change command' (YB) has to be turne ON to
reflect the changes of the input range, alert mode, or other settings. However, when 'Default setting registration command'
(Y9) is turned ON, the changes are reflected without turning ON 'Setting change command' (YB).
■Device No.
The following shows the device number of this output signal.
Signal name
Default setting registration command
Setting change command
Use this command to determine the values set in buffer memory areas (The buffer memory areas that can be set only in the
setting mode ('Setting/operation mode status' (X1): OFF)). ( Page 123 Buffer Memory Data Backup Function)
■Reflection of set values
Even though the set values are written into the buffer memory, they are not immediately reflected to the temperature control
module's operation.
To determine the set values, turn ON and OFF this command after the set values are written into the buffer memory.
Turning ON and OFF this command operates the temperature control module according to the setting in each buffer memory
area.
This device can be used as an interlock of 'Setting/operation mode command' (Y1).
■Device No.
The following shows the device number of this output signal.
Signal name
Setting change command
PID control forced stop command
Use this signal to temporarily stop the PID control forcibly.
■Mode of when the PID control stops
The mode of when the PID control stops is determined in "Stop mode setting" of "Control basic parameters" in "Application
Setting." ( Page 136 Application Setting)
If the CPU module is turned from RUN to STOP while 'CH1 PID control forced stop command' (YC) is ON,
'CH1 PID control forced stop command' (YC) turns OFF and the PID forced stop is cleared.
■Device No.
The following shows the device number of this output signal.
