Improvement in Rate-of-change Calculation Method
26
The specifications of the following I/O Units with a lot number 000426 XXXX
(manufactured on April 26, 2000) or later have been changed as shown in the
table below.
Model
CS1W-PTS01- • Improved effective resolution: From the equivalent of 10
V1 bits to 1/4096
• Improved rate-of-change calculation: See note 1.
CS1W-PTS02 • Improved effective resolution: From the equivalent of 10
bits to 1/4096
• Improved rate-of-change calculation: See note 1.
CS1W-PTS03 • Improved effective resolution: From the equivalent of 11
bits to 1/4096
• Improved rate-of-change calculation: See note 1.
CS1W-PTW01 • Improved effective resolution: From the equivalent of 10
bits to 1/4096
• Improved rate-of-change calculation: See note 1.
• Reduced 26-V consumption current: 0.4 A to 0.16 A
CS1W-PDC01 • Improved effective resolution: From the equivalent of 10
bits to 1/4096
• Improved rate-of-change calculation: See note 1.
• Added input range: 0 to 20 mA (See note 2.)
CS1W-PPS01 • Changed instantaneous value setting method and added
time unit setting function (See note 3.)
• Reduction of 26 V consumption current: 0.22 A to 0.16 A
CS1W-PMV01 • Improved resolution (answer back input): From the equiva-
lent of 9 bits to 1/2000
Before Change
The current process value was compared with the value before the time set by
the comparison time interval and the difference between them was divided by
the comparison time interval to find the rate-of-change per second. When the
difference was small, the calculated value turned out to be so small that it was
hard to identify the change.
After Change
The current process value is compared with the value before the time set by
the comparison time interval and the difference is output. When the difference
is small, the comparison time interval can be set longer so that the change
can be easily identified.
