Automatic setting monitor at input range change
The value set in 'Automatic setting at input range change' (Un\G302) is stored.
■Buffer memory address
The following table shows the buffer memory address of this area.

Control mode selection
Select the control mode for each control group. The control groups are divided into control group 1 (channels 1 and 2) and
control group 2 (channels 3 and 4), and share common settings within their group.
Normal mode
Set using bits 1 to 3 for each group.

• If the inputs are "internal", implement control using the process values detected by the internal inputs of the temperature
control module.
• If the inputs are "external", implement control using the value stored in 'CH1 Temperature process value (PV) for input with
another (external) analog module' (Un\G438). Temperature control module internal inputs are not used.
• If the outputs are "internal", implement control using the internal transistor outputs of the temperature control module.
• If the outputs are "external", implement control using the values stored in 'CH1 Manipulated value (MV) for output with
another (external) analog module'/'CH1 Manipulated value for heating (MVh) for output with another (external) analog
module' (Un\G407) and 'CH1 Manipulated value for cooling (MVc) for output with another (external) analog module'
(Un\G409).
• To enable the settings changes in normal mode, it is necessary to write the set values to buffer memory, and
then to turn OFF→ON→OFF again the settings change command (Un\G399, b11).
• Control mode cannot be changed while implementing controls. If changed, the changes will be reflected
when control stops.
