Examples for the data transmission options with frames

There are flexible customization options between the content of the variables in the central pro-
cessing unit and the data format on the other end. The "variables" column (see above screen-
shot) determines the data format within the central processing unit, the "data type" column
determines the data format in the Modbus frame or on the other end. They must not match. As
a result, type conversion can be carried out. The logical direction is displayed in the following
diagram:
Set selector in the "vari-
ables" column
NOTE!
For reading frames, the logical direction is the arrow to the left and for writing frames, the ar-
row to the right.
The permissible setting options include:

Only the configured bit is evaluated
2
Evaluates additional bits of higher integers
Selection/settings
Using the factor makes it possible to transmit floating point values in the integer
format. The transmitter multiplies the data with the corresponding factor before
transmission. The data must be divided by the same value in the receiver.

Description
This factor is used to rescale values dur-
ing the transmission, in particular, with
the same type conversions.
