Evento de perda de comunicação – Rapid SCADA 6.2.2

[isabellacog]

Boa tarde,

Estou utilizando o Rapid SCADA versão 6.2.2.0 e gostaria de esclarecer uma dúvida relacionada à geração de eventos de perda de comunicação com dispositivo.

Estou utilizando conexão via Modbus TCP e observei que, quando o dispositivo deixa de receber dados, os valores das tags ficam exibidos em cinza claro na tabela. No entanto, não identifiquei claramente como configurar a geração de um evento específico para indicar a perda de comunicação.

Minha dúvida é:

Existe alguma função ou configuração nativa na versão 6 para gerar automaticamente um evento quando o dispositivo ficar offline, ou é necessário implementar alguma lógica adicional (por exemplo, via script ou expressão)?

Poderiam, por gentileza, me orientar sobre a melhor prática recomendada para esse tipo de monitoramento?

Desde já agradeço o suporte.

There is a Status service tag for devices in the Communicator. This is probably the best solution.

Where can I find the ‘status’ service tag in the Communicator? I can’t find it.

[manjey73]

Just manually create an input channel in the device with the Status tag code in the database. Channel value 0 = Normal, 1 = Error

How would the formula look like? I tried this one, but it didn’t work: CnlStat == 0 ? 1 : 0.

[manjey73]

The formula is really weird and seems useless. What exactly do you want to do with the channel data?

This is a supervisory system for an operations center. So, when my device stops communicating, I need an alarm for that. If the formula is strange or incorrect, please show me the correct one. Otherwise, I would appreciate your help in clarifying it.

Hello,
Just create a new channel of the Calculated type, and set the Tag Code field to Status
The device field of the channel should refer to the certain device.
Then upload the project changes and check value of the newly created channel.
Provide a screenshot of your settings if it doesn’t work.

Using formula CnlStat > 0 ? 0 : 1 is also possible. But the method described above is simpler.

[isabellacog]

I did what you suggested. I created a new channel of the calculated type and set the tag code field to status. Now it is returning the value 1, but the device is off, so it should be returning 0, correct? Can you verify if I did something wrong?

[manjey73]

Status works differently, if it returns 1, it means an error. There is a Normal-Error Format for this.

[isabellacog]

The value of the channel status is not changing, and I can see in Device 1 that my device is changing in reality. Did I make any configuration mistake?

[manjey73]

21 – Input, data type – double or empty
Formula (script) none
Format – Normal-Error in table Normal; Error

I followed the steps, but it seems that the value of channel 21 stopped updating along with the other values when the device stopped communicating. I removed the ‘Normal-Error’ format just to observe which value would appear.

Show the channel settings with the Status tag again
