CSIOPCServer
Each device in the network map is represented by two tables in the statistics
device. The names of these tables are the result of appending the strings
“_hist” and “_std” to the device name.
The network controller also maintains statistics regarding the operation of the
communications server as a whole. These statistics are available in the
“_
_ LgrNet_ _ _ _controller_ _” table.
6.3.1 Device History Statistics
The name of a history table for a device is the result of appending the string
“_hist” to the device name. This table consists of three columns and has a row
size of 144. A new record for the table is generated every ten minutes. This
allows the table to describe the operation of the datalogger over the last 24
hours. The counters for this table are set to zero at the beginning of each ten-
minute interval. The columns for this table are as follows:
6.3.1.1 Attempts
Type: uint4
Description: Records the total number of communications attempts the device
made during the ten-minute interval. This counter is incremented by one
for every entry that appears in the communications status log and is
associated with the device.
6.3.1.2 Failures
Type: uint4
Description: Records the total number of communications failures that the
device experienced during the ten-minute interval. This counter is
incremented by one for every “F” record that appears in the
communication status log and is associated with the device.
6.3.1.3 Retries
Type: uint4
Description: Records the total number of retries that the device experienced
during the ten-minute interval. This counter is incremented by one for
every “W” record that appears in the communication status log and is
associated with the device.
6.3.2 Device “Standard” Statistics
The name of the standard statistics table associated with a device is the result
of appending the string, “_std” to the device name. This number of columns in
this table is variable depending on the device type and the version of the
LoggerNet server, although there are statistics that are common to all.
