Terminology
1.2.1 Analog value : A
A n a log value is a continuously changing value such as voltage, current, temperature,
speed pressure, flux, etc. Tem perature, for exam ple, is continuously changing according
to the tim e . Because this tem p e ra ture itself is not available for input of the PLC, the
tem perature should be converted an analog electrical signal by transducer. Moreover, the
converted analog signal (voltage or current) has to be converted into a digital value with
the A/D m odule because the PLC can handle only digital values.

Figure 1.1 Analog value
1.2.2 Digital value : D
D igital value is a discrete data that are described in num bers such as 0, 1, 2, … In
general, a binary code system that are consist of 0(off) and 1(on) is used for expressing
digital value. Also, BCD or hexadecimal values are used.
Because the CPU module of PLC can handle dig ital value only, the analog signal from
external devices should be converted into analog signals with A/D m o d u le.
In the other hand, the digital output of CPU m o d u le should be converted into analog
signal to be used for external devices. The D/A module (d igital-analog converter) is used
for converting digital values into analog output (voltage or current).

2.5 Processing specifications
2.5.1 Sampling processing A/D conversion system
The anal og values input to the channels designated for sampling processing by the CPU are
converted to digital output values one by one and the digital output values are stored in the
buffer memory.
As the A/D module scans each channel, the value appearing at the instant is written to the
buffer memory as a digital value. The timing of this sampling depends on the number of
channels used, and may be found from the following expression.
Process time = Number of channels used × Maximum conversion time (5 ms)
The process time when 4 channels is used, for example, will be 20 msec = 4 × 5 ms
2.5.2 Averaging processing A/D conversion system
The A/D module makes the A/D conversion for any channels to which averaging processing
has been specified from the CPU. Using a pres et count, an average is calculated (excluding the
maximum value and the minimum value) and stored to the buffer memory. The preset count
can be set as 2 to 255 times.
The time in which the average value by this processing is stored in the buffer memory varies
with the number of channels used.
Processing time = Count setting × No. of channels × 5ms (Max conversion time)
The processing time when count value is 50 and 4 channels are used, for example, will be 50 ×
4 × 5ms = 1000ms.

6.2 The Contents and description of buffer memory
6.2.1 G6F-AD2A
1)
Channel enable (Address 00)
- When the power is on, all bits are set as 0 (off) and all channels are disabled.
- In order to enable a channel, set the corresponding bit as 1 (on). For example, turn on
the bit 2 to enable the channel 2.
- Because the conversion time depends on the number of used channel, turning on just
necessary channel can reduce A/D conversion time.

Example) To enable channel 1 and 2 :
Write h0006 ( turn on bit 1 and 2 ) to buffer 00, and sampling time is
obtained as 2 × 5ms = 10ms.
2)
Output data range (Address 01)
- Only G6F-AD2A has the function of selecting the range of digital output data. (It is not
available with G3F-AD3A and G4F-AD3A).
- Each channel can be set independently.
- Turn on the corresponding bit as ‘1’ to set the output data range as -2048 ~ 2047. The
default value is ‘0’ ( -48 ~ 4047 ).
