TPL files - Microcom data definition file. Named per SNOTEL ID (nnnn.tpl), these files
define the Microcom GTX datafields used in the data extraction process. Each site,
transmitting data through a Microcom GTX data modem, must have a tpl file named for
its SNOTEL ID, placed in the application directory. MsiDCSdecode uses the tpl file to
understand the structure of each GTX GOES data message. If the configuration of the
data modem is modified, an updated tpl file must be placed in the working directory.
New in revision 2, msiDCSdecode understands GTX Min-Max-Avg (NXG) processing,
and will produce text labels for all NXG processed data points. The GTX NXG process
may produce up to 3 data points, one for each flag from the set: [NXG]. GTX will allow
you to include recent samples and NXG values within the GOES message data stream.
For example:
The GTX tpl statement: IL4=DYSI defines the label DYSI for internal sensor 4 (IL4).
The GTX tpl statement: MMA=0,I4,24:00:00,00:00:00,NXG tells the GTX to calculate
minimum (N), maximum (X) and average (G) values for internal (I) sensor number 4.
The GTX tpl statement: TDP=5,I4,2NXG,… tells the GTX to include in the data stream:
Two (2) recent sensor sample from the I4 sensor
The minimum (N) value of I4
The maximum (X) value of I4
The average (G) of I4 samples
msiDCSdecode will produce the following labels form the above statement set:
