8.3.26
Low-pass filter limit frequency (commissioning)
The second low-pass filter can be used for test purposes. Its function is identical to that of
the (operating) low-pass filter. An analysis of the signal curve after this low-pass filter can
provide additional information on the environment of the scales.
8.3.27
Low-pass filter number (commissioning)
The second low-pass filter can be used for test purposes. Its function is identical to that of
the (operating) low-pass filter. An analysis of the signal curve after this low-pass filter can
provide additional information on the environment of the scales.
8.3.28
Mean value filter depth
The mean value filter is used to steady the weight against random interference. The weight
is the mean value of n (n = max. 250) weights which are recorded by the weighing module
every 10 ms, e.g. when n = 10, the mean of 10 weights is calculated. Every 10 ms, the
oldest value is discarded and the newest value included in the calculation.
8.3.29
Display weighing range data
The weighing range data is relevant to operation with verification capability. The "Display
weighing range data" parameter is used to define whether the weighing range data is to be
output permanently in the "SecureDisplay" on the HMI. Alternatively, it can be displayed
separately using the command "802".
8.3.30
Interface for legal trade display
This parameter is used to define whether the legal trade display "SecureDisplay" is to be
made on a panel directly connected over Ethernet or via a SIMATIC CPU which is connected
to a panel.
8.3.31
Firmware version SecureDisplay
The version of the SecureDisplay software is entered in the "FW-Version SecureDisplay"
Parameter. If the version is not entered correctly, a scale value is not output on the
SecureDisplay, and the display indicates "Start Up".
