8.3
DR 3 Belt scale parameters
The belt scale parameters need to be checked and if necessary modified for all scales.
The fundamental function of the scale is defined by specifying the parameters and carrying
out the calibration. The parameters relevant to calibration can be protected against
modifications (write-protected) by means of a wire jumper at the P-PR (Parameter
Protection) terminals.
You must activate "Service mode" for the module in order to carry out any changes to the
data record:
● In SIWATOOL: in the command group "Service commands"
● From the CPU: using command code 1 (see chapter SIMATIC integration or Modbus
integration)
Procedure
● Read in DR 3, check all parameters, and modify them if required
● Transfer the DR 3 data record from SIWATOOL/SIMATIC/Modbus to the scale
● Carry out parameterization or calibration of the belt speed
● Calibrate the scale
● Transfer the DR 3 data record from the scale to SIWATOOL
A special feature distinguishes the WP241 module from other SIWAREX modules.
Every calibration command which results in a change in a parameter, e.g. during calibration
of the zero point or with calibration weights, initially leads to output of the result in DR 4. You
can check the result and subsequently import it into the DR 3 using an apply command. The
parameter becomes effective following importing into the DR3.
