Signal name
It is possible to designate the conversion enabled or disabled for each channel.
By disabling the conversion at channels not in use, generation of unnecessary wire
breakage detection flags may be prevented and sampling time may be reduced.
ON : Conversion enabled ..... wire breakage detection is conducted at the same time
the temperature of the target object is taken.
OFF : Conversion disabled .... neither temperature taking or wire breakage detection
is conducted.
CH.
By setting of conversion enable/disable, the following changes are made.
conversion
• When conversion is changed from disabled
enable flag
Temperature detection of the enabled channel is commenced.
After the detected temperature value of the corresponding channel is stored in the
remote register, the conversion completion flag of the corresponding channel is
turned on.
• When the conversion is changed from enabled
The conversion completion flag is turned off for the corresponding channel.
For the detected temperature value stored in the remote register, the data
immediately prior to the disable setting will be retained.
It is possible to designate the sampling processing or travel average processing for
each independent channel.
ON : Travel average processing
OFF : Sampling processing
In travel average processing, an average value of four detected temperature value

• When changed from travel average processing
The conversion completion flag is turned off for the corresponding channel.
After the most recent detected temperature value is stored in the remote register,
the conversion completion flag for the corresponding channel is turned on.
Note : This flag is only valid when the initial data processing completion flag
(RY (n+7) 8) or initial data setting request flag (RY (n+7) 9) is on.
