1.5 Embedded Functions
Functions of embedded analog module are as described below.
Function
Description
Channel Run/Stop
setting
● Specify Run/Stop of the channel to execute A/D, D/A conversion.
● If the unused channel is set to Stop, whole Run time can be reduced.
Input / output
voltage/current range
setting
● Specify analog input / output range to be used.
● Select range in parameter setting after selecting Voltage/Current input / output
according to the wiring properly.
● Embedded analog module provides two kinds of current input / output ranges
(4~20mA, 0~20mA) and four kinds of voltage input / output ranges (1~5V, 0~5V,
0~10V,-10~10V)
Input / output data
format setting
● Specify digital input / output type.
● 4 data formats are provided in this module.
(Unsigned value, Signed value, Precise value, Percentile value)
A/D conversion
methods
● Sampling processing
- Sampling process will be performed if A/D conversion type is not specified.
● Filter processing
- Used to delay the sudden change of input value.
● Average processing
- Outputs average A/D conversion value based on time or count.
● Detection alarm (Input disconnection)
- After detecting whether disconnection of the input circuit, the alarm is
displayed by a single flag.
(Input signal range : 4 ~ 20
㎃
, 1 ~ 5 V)
● Maintenance function of valid conversion value.
- When valid conversion value is exceeded, whether conversion value
retains will be able to set.
● Alarm function
- When exceeding valid input range, alarm and maximum /minimum flag
will be generated.
D/A output status setting
● Set the output status of channel when changing 'Run' to 'Stop'.
● The four kinds of output statuses (Previous, Min, Mid, Max value) are provided.
Interpolation method
setting
● Set linear interpolation, S-type interpolation method.
Detecting output
disconnection
● Detection alarm (Output disconnection)
- After detecting whether disconnection of the output circuit, the alarm is
displayed by a single flag.
(Output signal range : 4 ~ 20
㎃
, 0 ~ 20
㎃
)
1.5.1 Sampling Processing
It collects analog input sign through general A/D conversion processing at a specific interval to convert to digital. The time
required for A/D conversion of analog input sign till saved on the memory depends on the number of channels used.
(Processing time) = (Number of channels used) X (Conversion speed)
(i.e.)
If the number of channels used is 3, its process time will be
3 x 0.5
㎳
= 1.5
㎳
Sampling is to calculate the sampling value of continuous analog sign at a specific interval.
