Temperature sensor typeThe sensor type, input range, and scaling can be set individually for each of 2 inputs, which are each selectable from B, E, J, K, L, N, R, S, T, U, WRe5-26, PL II, and mV.
ScalingData to be stored in the allocated words in the CIO area must be scaled (with the minimum and maximum values set by user) (2 inputs set separately). For example, data can be stored at 0% to 100%.
Data storage in the CIO AreaThe value derived from carrying out the following processing in order of the actual process data in the input range is stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.

(input filter)
Calculates the moving average for the specified number of process values (1 to 128), and stores that value in the CIO Area as the process value.
Process value

Adjustment
period
control
When zero/span adjustment is executed, the date is internally recorded at the Unit. When the preset zero/span adjustment period and number of days notice have elapsed (allocated in Expansion Setting Area), this function turns ON a warning flag to give notice that it is time for readjustment.
Peak and bottom
detection
This function detects the maximum (peak) and minimum (bottom) analog input values, from when the Hold Start Bit (output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF, and stores them in the Expansion Control/Monitor Area.
Top and valley
detection
This function detects the top and valley values for analog inputs, from when the Hold Start Bit (output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF, and stores them in the Expansion Control/Monitor Area.
