CH1 Input range
Select corresponding setting values from the temperature sensors used with the temperature control module, temperature
measuring range, temperature unit to be output (Celsius ()/Fahrenheit ()/digit) and resolution (1/0.1).
For inputs from other analog modules (such as an A/D converter module) also, set these values.
Ex.
When selecting the following thermocouple:
• Thermocouple type: R
• Temperature measuring range: 0 to 1700
• Resolution: 1
Set 'CH1 Input range' (Un\G501) to 1.
■Buffer memory address
The following shows the buffer memory address of this area.

■Setting value and type of thermocouple
The following table lists the setting values of 'CH1 Input range' (Un\G501) and the corresponding thermocouple types. The
relation between each temperature unit and setting value is also shown as follows:
