DR 45 protocol request
8.23.1
Overview
Scale logs can be saved in the internal memory of the SIWAREX. If necessary, a log can be
read out calibration-proofed using the SIWATOOL V7 program or the SecureDisplay and its
contents checked.
Using data records DR 45/DR 46, you can read all logs into the SIMATIC S7 (not calibration-
proofed, only as operating information). The users enters the desired protocol ID in DR 45
and subsequently sends DR 45 to the SIWAREX. The protocol is then made available in DR
46 for reading out.
