2 Analog I/O Modules
■ Data Format
The analog input value can be handled as the set data format. There are seven data formats for the analog inputs.
YES: Supported, NO: Not supported

Optional range
Scales the analog input value to a digital value with 12-bit or 16-bit resolution in the specified minimum and maximum
value range (-32,768 to 32,767) and stores it in the data register.
However, when PTC Thermistor (threshold) is selected as Signal Type, the range of the minimum and maximum
value is 100 to 10,000.
Example: The digital resolution data is 12bit, the range of the input voltage value is -10 to +10V DC, the minimum
is -1000 and the maximum is 1000.

*1 Binary data (12bit) and Optional range (12bit) are displayed only for FC6A-J8A1 and FC6A-J8A4.
*2 Can only be set when Signal Type is thermocouples, resistance thermometers or NTC Thermistor.
*3 Resistance when using the FC6A-J8CU1 or FC6A-J8CU4 and Signal Type is set to PTC Thermistor or Ohm meter.
*4 Binary data (16bit) and Optional range (16bit) can be used with the following versions.
FC6A-J8A1, FC6A-J8A4: Hardware version 200 or later (Refer to " Checking the Hardware Version Number" on page 2-2.)
If an FC6A-J8A1 or FC6A-J8A4 that does not correspond to the above version numbers is set to Binary data (16bit) or
Optional range (16bit), an error will occur and the module will operate as Binary data (12bit).
