Conversion Details
The following paragraphs discuss details about the conversion
program methods and results.
I/O Configuration
PDS2WIN converts I/O configuration files created by versions
2.7 through 2.95. All module types, chassis and slot positions,
point tag names and descriptions are converted.
Analog Alarm Limits
The alarm limits for analog modules are not converted. In
W
INTERPRET , alarm limits are now configured as part of
analog scaling function blocks. This allows you to express the
analog alarm limit values in terms of engineering units
instead of raw analog units (0 to 4095).
Comm Protection, Initial Values and Final Values
The comm protection flag for all variables is set to “not
protected.” All initial and final values are left empty.
Line Monitored Input Modules
The fault LED states for line monitored input modules are
determined by the tags for points 17 to 32. If the points are
not tagged, the LEDs are disabled. The threshold values for
line monitored input modules are converted from the 2.9x
defaults.sys file. The following formulas convert the 2.9x
values to W
INTERPRET values:
open threshold = ((high threshold * 37) / 255) - 5,
on/off threshold = ((middle threshold * 37) / 255) - 5,
short threshold = ((low threshold * 37) / 255) - 5.
When defaults.sys is not present, the following are the
threshold values:
open threshold = 20,
on/off threshold = 12,
short threshold = 4.
