Temperature sensor type The 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.
Scaling Data 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 Area The 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.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits

The process value overrange direction for when a disconnection occurs can be specified. (High: 115%
of set input range; low: -15% of set input range)
Function Mean value
processing
(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 alarm Process value 4-point alarm (LL, L, H, HH), alarm hysteresis, and ON-delay timer (0 to 60 s) are
available.
Rate-of-change
calculation
Calculates the amount of change per comparison time interval (1 to 16 s).
Rate-of-change
alarm
Rate-of-change 2-point alarm (L, H), alarm hysteresis (shared with process value alarm), and ON-
delay timer (0 to 60 s, shared with process value alarm) are available.
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.

and by photocoupler for signals.

Unit, errors related to the CPU Unit, and use of external power supply).

* The method for calculating the error in temperature measurements, including the temperature coefficient, is given
   below. The "full scale of electromotive force" is the difference between the high limit and low limit converted to
   electromotive force for each thermocouple.
