■ Conversion type
Configures the data type of the device address to which Present_Value is allocated. For details, refer to Present_Value
in “Analog Value Object” on page 3-138.
■ Coefficient
The product of Present_Value multiplied by 1/coefficient is stored in the device addresses allocated as Present_Value
for reading.
Present_Value for reading = Present_Value × (1/coefficient)
When the device for write trigger is changed from 0 to 1, the product of multiplying the value of the device addresses
allocated as Present_Value for writing by the coefficient is set as Present_Value.
Present_Value = Present_Value for writing × Coefficient
The coefficient is multiplied as a float-type value. The conversion order is as follows.
Present_Value → Device Addresses
(1) Present_Value is multiplied by (1/coefficient).
(2) The data type of the result of (1) (Float32(F)) is converted.
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).
