Chapter 13 Built-in Analog Function
You can set an output status of channel among Previous, Min, Mid, Max value.
(a) Previous value: The last output operated normally is retained.
(b) Min: The Min value of each range is outputted.
(c) Mid: The Mid value of each range is outputted.
(d) Max: The Max value of each range is outputted.
(3)
Example
When the range of output channel is set by 4 to 20 mA and the output is 10 mA, and then if the system is
changed from 'Run' to 'Stop', the output will be as follows depending on setting data of channel output status.
(a) Previous value: 10 mA which is previous output value is retained.
(b) Min value: 4 mA which is min value of relevant range is outputted.
(c) Mid value: 12 mA which is mid value of relevant range is outputted
(d) Max value: 20 mA which is max value of relevant range is outputted.
13.5.8 Interpolation Method Setting
(1) Functions
The output signal of module is used in order to execute interpolation output depending on set interpolation time.
When the voltage and current is outputted, it can be used to prevent transient response of load system as a suddenly
changed output.
(2)
Interpolation method setting
Interpolation method can set the one among interpolation prohibition, linear interpolation S-type interpolation.
(a) Interpolation prohibition: It doesn't execute interpolation operation. And it outputs digital input value intact.
(b) Linear interpolation: The output is changed up to objective value with linear during the interpolation time.
