Table 5-4 Allocation of DR 7
5.6.1 DR 7 - Source for the Weight Simulation
Instead of the
actual weight determination, a weight simulation can be activated for
test purposes. The simulated weight value can be defined through the SIMATIC
interface or through the RS232 interface (SIWATOOL FTC). The weight simulation
makes commissioning the scale much easier in certain situations.
5.6.2 DR 7 - Decade for Rounding the Decimal Places for the Process Values
This pa
rameter can be used to define to how many decimal places that the
(weight) process values should be rounded. This entry decouples the display of
weight values which trigger the restrictions of the calibration requirements from the
values that are used in the control software.
5.6.3 DR 7 - Force in Service Operation
After activating this functio
n, the digital outputs can be forced independent of their
parameter definitions. Force control is only possible in service operation and only
with the SIMATIC interface.
