DR 7 Allocation
5.6.1 DR 7 - Source for Weight Simulation
Instead of the actual weight determination, a weight simulation can be activated for
test purposes. The simulated weight values can be defined over the SIMATIC
interface or the RS232 interface (SIWATOOL FTA). The weight simulation makes
commissioning a scale much easier in certain situations.
5.6.2 DR 7 - Decade used for rounding the decimal places of the process values
This parameter 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 and the
values that are used in the control software.
5.6.3 DR 7 - Force in Service Operation
After activating this function, 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.
!
Warning
Before using this function, you must ensure that the system will not achieve any
hazardous state that could be caused by forced control of digital outputs of the
SIWAREX FTA.
