Out of Range Channel Data Mask

[cooldjmc]

Hi,

Is it possible for Rapid SCADA to handle out-of-range channel data read from a device? For example, if a channel reads 0xFFFFFFFF (4294967295), could it display “–” or another designated character instead of the numerical value?

The desired behavior is to display a mask, such as “++++” or “—-“, whenever a received value falls outside the expected range for that channel.

Thank you

Send a channel to the double.NaN and you will see ---

Hi, please can you be more specific, where I must set the double.NaN in comunicator or a channel formula?

Thank you.

In the input formula of the channel, you can check for an input value greater than 100 example
Cnl > 100 ? double.NaN : Cnl

Or write a more complex formula and add it to the Script tables and call it in the input formula.

Hi,
Conversion should be made using channel formulas as written above.
