Allocation of DR 47
5.29.1 DR 47 - MMC-ID
Identification of the MMC card.
5.29.2 DR 47 - Log ID
The log ID is a unique log number that can be used to identify the log. The number
is incremented with every logging procedure.
5.29.3 DR 47 - Last log data
The output log consists of 4 strings.
5.30 DR 120/121 Trace - Data logging
Measurement values and actual states in the weighing process can be stored in
RAM memory of the SIWAREX FTA or in the MMC card with the trace function.
When recording to RAM, SIWATOOL FTA reads the trace elements through data
record 120, when recording to MMC through data record 121.
The recording can be started with the "Start Recording" command
with "End recording" command 71.
By defining parameters in data record DR 7
be defined. The data record cannot be read through the SIMATIC CPU.
