Enter the tag name to be displayed in the Chart and Indicator Views and
used to identify the channel in archive files (20 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.
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.
