Enter the tag name to be displayed on channel indicators and
used to identify the channel in archive files (8 characters max.).
Note.
Tags with a high percentage of capital letters and wide
characters such as 'W' or 'M' may appear truncated in some
Operator Views. In such cases, use lower case letters or fewer
characters.
Enter the tag name to be displayed in the Process view and
used in the archive files (20 characters max.).
Set the time period over which the process variable is to be
filtered prior to being sampled (0 to 60 seconds).
Set a tolerance level (between 0 and 100 % of the engineering
range) to allow for deviation of the input signal above or below
the input span before an input failure is detected.
Example
– setting the fault detection level to 10 % on an input
range of 50 to 250 bar causes an 'Analog Input Failure' fault to
be detected below 30 bar and above 270 bar.
In the event of an input failure, recorder channels can be set to
drive upscale, downscale or in the direction of failure.
Upscale
– channel value driven beyond full scale.
None
– driven in direction of failure.
Downscale – channel value driven below zero.
