Dynamically display text in a text field

[dejan]

Is it possible and how to display a text message that is dependent on the input channel value? For example, if the channel value = 1, display text = “Message 1” and if the channel value = 2, display text = “Message 2”.

Hi,

It’s easy. Add your messages to Units table like “Alarm states 1” record. Then select created unit for an input channel with Discrete channel type and Text format.

1st message is 0.0 (value)
2nd message is 1.0
etc.

Mikhail, for me personally your answer is not clear. You propose to operate with units but….. how to create formula with reference to the different units?

I also tried to create input channel (type of channel=”Calculated tele signal”, format=”Text”) which outputs text values using following function (for dynamic outputting text values in the Web-browser):
MyMode(GetBit(Val(308),1)) – here I read value from channel 308 (it ‘working OK) and try to get text for output value.

public String MyMode(double val)
{
if (val==0.0)
{
return “Stop”;
}
else
{
return “Running”;
}
}

But the formula is not working (in diagnostic windows everything is OK) and I feel that my way is wrong…..
What’s wrong?

Now it’s clear:

1. In new string of Unit table in column “designation” put for instance “Alarm state 1; Alarm state 2”
2. Then select created unit for an input channel with Discrete channel type and Text format;
When applying text format for input channel that means using unit text instead of digital values!

In this case if input channel value(also one can use formula) is equal 0 then appears message “Alarm state 1”, if value= 1 then “Alarm state 2”.

Definetely! Thanks for the clarification 😉
