Hi All,

I have some confusion regarding Analog Input Channel.

For example, I am getting analog signal from sensor as 4-20 ma and from I to V converter I am getting 1 to 5 volt which is applied to my 10 bits analog input port.

Now I want to get actual value = 0 for input 1 volt and actual value = 100 for input 5 volt. When input is less than 1 volt i.e. current is less than 4 ma, there is some thing wrong in sensor.

Now tell me please how configure analog input channel object to get value said above.

I have set parameter as follows

RawValRangeLow = 0
RawValRangeHigh = 1023

ChannelSigValLow = 0
ChannelSigValHigh = 5

SensorSigValLow = ???
SensorSigValHigh = ???

ActValRangeLow = 0
ActValRangeHigh = 0

Thanks & regards

Hi Jags,

SensorSigValLow = 1
SensorSigValHigh = 5

ActValRangeLow = 0
ActValRangeHigh = 100

will give the desired conversion.
