3.4.5 CH[ ] Measured temperature value (Un\G11 to Un\G18)
“Thermal electromotive force values” input from thermocouples are converted into
“temperature values” to check values of detected temperature.
(1) Data storage
The measured temperature value rounded off to one decimal place is multiplied by 10
and the result is stored into buffer memory in 16-bit signed binary. (Drop the second
decimal place and later.)
[Setting example 1]
When the measured temperature value is 123.025 1230 is stored.
Figure 3.23 Storage example 1 of CH Measured temperature value (Un\G11 to Un\G18)
When the measured temperature value is -123.0 -1230 is stored.

POINT
(1) When disconnection is detected or checked with a monitor, the values set in
Conversion setting for disconnection detection (Un\G164, Un\G165) or
Disconnection state conversion setting (Un\G164, Un\G165) are stored into
the CH Measured temperature value (Un\G11 to Un\G18). (Refer to Section
3.4.25, Section 3.4.26)
(2) After the disconnection recovery, normal measured temperature value is
automatically stored.
(3) Use Conversion completion flag (XE) or Conversion completion flag (Un\G10)
as an interlock to read out the measured temperature value.
