Record size
Shows the size of the file record for a single channel or
section. It is set automatically depending on the file and
on the number of parameters in the data record
Parameters
Defines the number of parameters in a single data
record for data log files.
Memory is allocated for each file statically and does not change unless you re-
organize the files. The PM180 automatically performs de-fragmentation of the
memory each time the file allocation changes. This helps keep all free memory in one
continuous block, and thus prevents possible leakage of memory caused by
fragmentation.
In the EN 50160 version, data log files #9 and #10 are automatically configured for
recording EN 51060 compliance statistics and harmonics survey data. You may not
change the record structure, but can change the amount of memory allocated for
each file.
Data log files #15 and #16 may be configured to record TOU monthly profile and
TOU daily profile data on a daily or monthly basis.
To change the file properties or to create a new file:
1. Double click on the file partition you want to change, or
highlight the file row, and then click on the “Configure File”
button.
2. To change the file properties, select desired parameters, and
then click OK. For your reference, the record size and the
number of records available for the file are reported in the
dialog box.
3. To delete a file partition, click on Delete, and then click OK.
4. Send your new setup to the device.
The following table shows how to calculate a file size for different files.
