Display of current data value

[derinder]

Dear Sir,

I have observed that , if we stop the communicator service, and keep the server on… then also at web display we get last values at current column display …

if we switch off the server … all values goes off (it is as expected).. but the previous case it looked strange.

Regards,

Hello,

If Communicator is off, the values become undefined in 5 minutes by default. You can change this time span by the parameter “Unreliable on inactivity” in SCADA-Server.

Dear Sir,

I have tried it… it changes the colour of current data values … but still it shows the values (this can be confusing sonme time)… also if we click for charts… colour of the main graph is matching so one can not distinguish between true and false data. it creats confusion.

I think unreliable values should not come in graph or should come with different colour…

Regards.

Good idea, thank you.
I’ve added it to the issue list.

If it is critical to your project, it is possible to change the Unreliable status to Undefined by a formula of input channel.

1. Create a formula in the Formulas table:

int CorrectStat()
{
  return CnlStat == 5 ? 0 : CnlStat;
}

2. Add the expression in the Formula field of an input channel:

Cnl; CorrectStat()

Note: I didn’t test this answer. It should work, but may have mistakes.

Please, provide your value of the formula field of the input channel.
