13-2 Data Logger Functional Block
The Data Logger Functional Block
The Data Logger functional block allows you to control the DL-10 device's data
logging ability. The DL-10 hardware platform is identical to the SCH-10
hardware platform, but the two devices run different applications. You can
convert an SCH-10 device into a DL-10 device by downloading a DL-10
application into it, and vice versa.
The DL-10 application filters and logs data into up to three logs in a DL-10
device. The LonPoint Data Logger Utility allows you to upload these logs from
the DL-10 device to a comma delimited text file and export the file to a trending
application such as Wonderware InTouch. See The LonPoint Data Logger
Utility, later in this chapter, for more information. The following figure and
tables summarize the inputs and outputs of the Data Logger functional block:
Input Network Variables
Default name Default type Description
DataIn(1-7) SNVT_str_asc
(changeable)
One of seven data input network
variables. Multiple network
variables may be connected to each
input. Any of the seven inputs may
be stored in any one of the three
logs.
Enable(1-3) SNVT_switch One of three Enable network
variables corresponding to the
three logs. If the Enable network
variable for a log is set to Off, the
log will not record data. If the
Enable network variable for a log is
set to On, the log will function as
normal.
Clear(1-3) SNVT_switch One of three Clear network
variables corresponding to the
three logs. If the Clear network
variable for a log is set to On, the
log will be cleared.
