3.5.6 Approach flag (buffer memory address 17, 18: Un\G17, Un\G18)
(1) This flag checks if the measured value (PV) is within approach band.
(2) When the measured value (PV) is within approach band, the flag is "1".
Also, when the soak time (buffer memory address: 168) is set and the
measured value (PV) stays within approach band in the set time only, the flag is
"1".
3.5.7 Set value (SV value) monitor (buffer memory address 25, 26: Un\G25, Un\G26)
(1) The current value of set value monitor is stored.
The transitional change of set value during the program control is monitored
when setting the setting change rate limiter (buffer memory address: 52, 84).
3.5.8 Cold junction temperature measured value (buffer memory address 29: Un\G29)
(1) The measured temperature of cold junction temperature compensation resistor
mounted on Q62HLC is stored.
The value to be stored is in the range of –10 to 100 (-10 to 100
).
3.5.9 Control mode monitor (buffer memory address 30: Un\G30)
(1) When control mode, the switching value of control mode is stored after the
completion of shifting.
The value is configured with data of each channel 4 bits and stored in the lower
8 bits of buffer memory address 30.
The value of channel 1 is stored in 0 to 3 bits, and the value of channel 2 is
stored in 4 to 7 bits.

(3) Set the manipulated value (MV) in manual control mode 1 and manual control
mode 2 after checking that the stored value is changed to 1 or 3.
