Weighing Functions - Siemens SIWAREX FTA Device Manual

5 Weighing Functions

5.1 General Information
The SIWAREX FTA can be used either as a non-automatic weighing instrument or
an automatic weighing instrument. The operating mode is determined by the
application and is defined during scale commissioning.
The selected operating mode and the defined parameters are very important to the
behaviour of the SIWAREX FTA in the process.
The parameters are set with default values from the manufacturer. Using the "Load
default values" command, the parameter definitions defined in manufacturing are
loaded.
The default parameters are defined so that the scale is immediately ready for each
operating mode. Not all parameters must be re-entered for each operating mode.
By changing a parameter, the behaviour of the scale is changed respectively. The
advantage of this solution is that you can define how many default values should
be retained and how much that the behaviour of the scale has to be changed for
the application.
All parameters are split into data records (DR). The data records are organised
according to process steps (tasks) that you have to perform during the
commissioning phase or during the process itself.
In the following parameter description, you will find a description of the weighing
functions that are influenced by that parameter.
The parameters of a data record are shown in a table to start with. This is then
followed by the exact parameter description for the parameters of that data record.
After receiving a new parameter, SIWAREX FTA runs a plausibility check. If there
is a parameter error then the data record will not be accepted (stored) by the
SIWAREX FTA and a "synchronous" message is generated (see chapter
Messages and
SIWAREX FTA
Diagnostics).
