Temperature sensor type | The sensor type, input range, and calibration can be set individually for both inputs, each of which can be selected from B, E, J, K, L, N, R, S, T, U, WRe5-26, PL II, and mV. |
Calibration | To be stored in the CIO area, the assigned word data must be calibrated (using the minimum and maximum values set by the user) (2-point input is set respectively). For example, data can be stored at 0%~100%. |
Data storage in the CIO Zone | By performing the following processing sequentially by the actual process data in the input range, the derived values will be in four-digit hexadecimal (binary values)
The form is stored in the assigned word in the CIO zone.

When a broken line occurs, the process value can be specified in the direction of the out-of-range. (High: 115% of set input range; Low: -15% of set input range) |
function | Average Processing (Input Filter) | Calculate the moving average of the specified number of process values (1~127) and store the value in the CIO area as the process value. |
Process value alarms | Process value 4-point alarm (LL, L, H, HH), alarm hysteresis and ON delay timer (0~59s) can be used |
Rate of change calculation | The amount of change in each comparison interval (1~15s) was calculated. |
Rate of change alarm | Rate of change 2-point alarm (L, H), alarm hysteresis (shared with process value alarm) and ON delay timer (0~59s, shared with process value alarm) can be used. |
Adjust cycle control | When a zero/span adjustment is performed, the date is internally recorded in the cell. In the event that the preset zero/span adjustment period and the remaining number of notification days have expired (allocated in the extended settings area), this feature will turn on a warning sign to notify that it should be readjusted. |
Peak and minimum value detection | This function will detect the maximum (peak) and minimum (lowest) analog input values, turn on (ON) and off (OFF) from the hold start bit (output) assigned to the extended control/monitoring area, and store them in the extended control/monitoring area. |
Top and valley detection | This function will detect the top and valley values of the analog input, from the hold start bit (output) assigned to the extended control/monitoring area
ON until OFF and store it in the extended control/monitoring area. |
