For any changes to the settings of the configuration of logging a Group (e.g.
a change in the logging parameters, changing parameters of
Display options
parameter block or change parameters of Logical channel included in logging
Group) creates a new logging file. If the user shuts down the device or changes
other parameters independent of logging Group, a new logging file is not created.
At the time of saving, reverting configuration or loading configuration from a flash
drive, the logging is held, which will cause the absence of samples in logging files.
An accurate description of data structure which is saved during logging is in chapter
7.14.3.

Single channel - one big needle.
Task:
The task is to create a Group with only one logical channel. The value of that channel
should be displayed in the whole screen in the needle mode.
Solution:
Let's assume that we have configured a logical channel in the Hardware input Mode for
the RTD module. The logical channel is named Temperature and it displays heater
temperature (example of logical channels configuration is shown in
Chapter 7.8.11.
Examples of Logical Channels configuration
, especially see
Example 7.8.11.3.
Application of Logical channel in the Hardware input mode for RT4 modules
We need to define a Group with a logical channel in order to display it on the device
screen. To do that:
–
enter the
Groups
menu and turn on
Group 1
if it is turned off,
–
in the
Name
parameter write
Heater
,
–
for
Channels
parameter block:
•
Slot 1
parameter set as
Logical channel 1
named
Temperature
,
•
Slot 2 ÷ 6
set as
disabled
,
–
all the other parameters should be on default settings,
Next we need to define the Initial view. To do this:
–
enter
the General settings
menu,
–
for
Initial view
parameter block:
•
Display mode
parameter set as
needles
,
•
Displayed group
