12.2 Calibratable main weight display
The calibratable main display for SIWAREX FTA can either be done on a
calibratable S 102 display (company Siebert) or when using SIMATIC S7 Classic
with certain standard SIMATIC OP/TPs (0). The application conditions and details
can be found in the design certification for SIWAREX FTA.
12.3 Reading the calibratable logs with SIWATOOL FTA
The weighing log can be created on a calibratable printer or in the calibratable
memory in the optional Micro Memory Card.
The capacity of the MMC should normally be sufficient for recording the scale logs
for a period of 3 months. The MMC can be configured with SIWATOO FTA so that
the data will overwrite older data when the memory is full. This creates a circulating
buffer that conforms with the documentation of the calibration regulations.
A unique log ID is found in every weighing log that is stored. The log ID is very
important because it is also printed out on the non-calibratable delivery note next to
the amounts.
If anyone objects to a fixed delivery because of the delivered amount, the log ID is
used to help find the log - either in a stack of paper logs or on the Micro Memory
Card.
The SIWATOOL FTA is connected with SIWAREX FTA for this reason. After
entering the log ID, the data to be checked is read from the MMC, which is still in
the SIWAREX FTA and is continuously storing the production scale data, and this
data is then displayed.
