DR 45 Protocol request

8.35.1

Overview

A total of 550,000 weighing logs can be saved (in a calibratable manner) in the internal
memory of the SIWAREX. If necessary, a log can be read in a calibratable manner using the
calibratable "SecureDisplay" display software and its contents checked.
Data records DR 45/DR 46 can be used to read any log to SIMATIC S7 (not calibratable,
only as an operating display). The user enters the protocol ID for the desired log in DR 45
and then sends DR 45 to the SIWAREX. The log is then made available in DR 46 for
reading. Command 891 is used for the calibratable display of logs by the calibratable
"SecureDisplay" software.
