Siemens SIWAREX FTA - DR 7 - Memory Segment for Trace Function

Weighing Functions
SIWAREX FTA
5-86
Bit 2 defines which memory is used for recording the trace data.
0: Trace data is stored in RAM
1: Trace data is stored in the MMC
The trace function is described in 5.6.29
5.6.27 DR 7 - Memory segment for trace function
The MMC memory can be used for recording the trace data and for recording the
calibratable scale logs.
The percentage of MMC memory that is available for the trace function is defined
with this parameter.
Up to 100% is permitted in this definition but the total for trace function and
calibratable log may not exceed 100%
The trace function is described in 5.6.29
5.6.28 DR 7 - Memory segment for log
The MMC memory can be used for recording the trace data and for recording the
calibratable scale logs.
The percentage of MMC memory that is available for the calibratable logs is
defined with this parameter.
Up to 100% is permitted in this definition but the total for trace function and
calibratable log may not exceed 100%
The trace function is described in 5.6.29
5.6.29 DR 7 - Trace function recording cycle
Every n-te measurement (n x 10 msec) is recorded. When recording to RAM, n ≥ 1
is possible and when recording to MMC, n ≥ 5 is possible.
The recording can be started with the “Start Recording” 70 command and stopped
with “End recording” 71 command.
A recording element has a length of 64 bytes and contains several measurement
values and status bits.
