Specifying Signal Conditioning in Database

Manager

With the Database Manager Signal Conditioning field, you can specify the method

for converting raw data to a value that FIX/iFIX applications can use. Once you

select a signal conditioning, the driver scales (converts) the data to a value within the

specified range.

Unsigned 8- and 16-bit data types support all types of signal conditioning; signed 8-

and 16-bit values only support LIN signal conditioning. Other data types, such as

DWORD, DINT, REAL, ASCII or STRING, do not support signal conditioning.

Timers requires TBCD signal conditioning and counters require 3BCD signal

conditioning.

The type of signal conditioning you select must match the range of incoming values

from the process hardware. By matching the range of values in the process hardware,

you ensure the driver can properly convert the raw data values to the database block’s

EGU range. For example, if the incoming values are between 0 and 255, you would

select 8BN signal conditioning.
