1 OVERVIEW
(7) Changing the input range
The input range 3 can easily be set from the GX Developer.
3 Input range refers to the type of offset/gain settings. The most frequently
used range is set as the default but the user can also set the offset/gain.
(8) A/D conversion system
There are the following five A/D conversion systems.
(a) Sampling processing
Analog input values are converted into digital values one by one on a
channel basis and the digital output value is output at every conversion.
(b) Averaging processing
1) Time averaging
A/D conversion is averaged in terms of time on a channel basis and a
digital average value is output.
2) Count averaging
A/D conversion is averaged in terms of count on a channel basis and a
digital average value is output.
3) Move averaging
The specified number of digital output values measured per sampling
time are averaged.
(c) Primary delay filter
A digital output value is smoothed according to the preset time constant.
(9) Input signal error detection function
The voltage/current outside the setting range is detected.
(10) Warning output
There are the following two warning outputs.
(a) Process alarm
A warning is output if a digital output value falls outside the setting range.
(b) Rate alarm
A warning is output if the varying rate of a digital output value falls outside
the preset varying rate range.
(11) Online module change
The module can be changed without the system being stopped.
Further, the dedicated instruction (G. OGLOAD, G. OGSTOR), write to the buffer
memory, or turning ON the Y signal enables "inheritance of offset/gain settings to
the new A/D converter module replacing the old one changed online" and
"transfer of offset/gain settings to the other A/D converter module mounted on the
other slot". (These apply to the modules of the same model.)
