DATA CONVERSION

I 0 – 100% DATA CONVERSION

Analog input data is converted into digital representations of 0 – 100% proportional to each scaled range. The converted %

values are multiplied by 100 and expressed in 16 bits.

Overrange input is possible from -15 to +115% of the nominal range. When the signal exceeds the limit, the data is fixed at

-15% or +115% respectively. Negative value is represented in 2 s complements.

Converted Data, Hex

Analog output is converted in the reverse order of the input data. The output range 0 – 5 V DC is expressed as 10000 at

5.0 V (100%) and 0 at 0 V (0%).

I ENGINEERING UNIT CONVERSION

Engineering unit value °C or K is multiplied by 10 and expressed in 16 bits. °F data is represented in engineering unit

value, without multiplication. Engineering unit value A is multiplied by 100 or 1000, expressed in 16 bits. Negative value

is represented in 2 s complements.

■ COUNT VALUE

The count value is 32-bit data. It is divided in 2 words of 16 bits represented with 2 addresses.The lower address is

The maximum count value available is 1 000 - 4 294 967 295. In case of overflow, the vaule is reset to 0 or 1

(configurable) from which the count will restart. The preset of the count value is also available. Use the R7CON or

host PC/PLC for the configuration.
