3.4.5 CH[ ] Measured temperature value (Un\G11 to Un\G18)

CH[ ] Measured temperature value (Un\G11 to Un\G18)
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.)

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.
