■ Device for Present_Value
Configures the device address to store Present_Value.
According to Conversion type, 1 or 2 continuous words of address number are used starting from the specified
address number of Device Address.
■ Conversion type
Configures the data type of the device address to which Present_Value (float) is allocated. For details, refer to
Present_Value in “Analog Input Object” on page 3-136.
■ Coefficient
Configures Present_Value as the product of the value stored in the device address multiplied by the coefficient.
Present_Value = Value stored in the device address × Coefficient
Example:
The coefficient is multiplied as a Float32(F) value. The conversion order is as follows.
Device Addresses → Present_Value
(1) The value of the device addresses is converted to a
Float32(F) value.
(2) The coefficient is multiplied by the conversion result in (1).
