When all possible substitution tokens (9) are used you will have just 7 characters left to customize the file
name, but you could manipulate the file by specifying the
“system/driver” names wisely. i.e. use the
“system name” for unique system identification and the “driver name” as a common file name part.
4.22.7 Verification
To check if the file is fully transferred the data logger will verify if the transferred file has the expected file
size. If the transferred file is removed to quickly by some FTP-client or if the FTP-server does not allow
the
file size command the verification will fail and you have to switch this option to “Off”. When switching
off verification there is a limited chance on data loss, it
’s at your own risk (Note: All log data is still
available on the SD-card).
4.22.8 Input parameters
An FTP-client is able to transmit up to 8 different parameters to the data logger. Such a parameter can,
like any other sensor parameter, be logged, alarmed up on or used in a derived channel (e.g. a calculated
channel that evaluates to an alarm condition, in example when a level exceeds x and flow exceeds y).
The FTP-client should place the file with input parameters on the FTP-server in the same directory where
data log files are transferred to.
The name of the file should be formatted as
YDOC_<SN>.dat
and contain one or multiple lines separated
from each other with a carriage return or carriage return line feed, with one <
name>=<value>
pair per
line. The name should match with a parameter code of one of the defined input parameters.
e.g.
MAXLEV=3.2
MAXFLOW=4.5
The decimals should be separated with a dot.
The data logger will remove the file from the server once processed
.
4.22.9 Remote configuration and firmware upgrade
As of FW V4.5B3 its possible to update the data logger configuration or upgrade the FW by placing a file
on the FTP-server in the same directory where data log files are transferred to.
The names of the files should be formatted as follows:
•
YDOC_<SN>.bin
for a FW file.
•
YDOC_<SN>.cfg
for a config file, this can be a complete binary configuration file or a file
containing just some changes by means of tiny configuration snippets (See chapter configuration
snippets).
The data logger will remove the file from the server once processed.
