Changing the value of a tag if another tag changes state

[AntonioFar]

Hi,
I need to monitor a certain tag, specifically I am monitoring a tag that records a temperature.
I would need to set a boolean tag to 1 when a certain temperature threshold is exceeded. When the problem returns, I would need to reset the boolean tag to 0.

How can I set this condition with Kepware?

Greetings @AntonioFar 

Certainly! To achieve this in Kepware, you can use the Advanced Tags feature. Here’s how you can set up the condition:

1. Create an Advanced Tag:

   • Open the KEPServerEX configuration.
   • Launch the Advanced Tags section.
   • Create a new Advanced Tag that will act as your boolean tag.

2. Link the Temperature Tag:

   • Link the temperature tag (which records the temperature) to the Advanced Tag.
   • Set up a trigger based on logical states. For example, when the temperature exceeds the threshold, the Advanced Tag value changes to 1.

3. Reset the Boolean Tag:

   • To reset the boolean tag when the problem returns, you can create another trigger based on the temperature returning to a safe range.
   • When the temperature drops below the threshold, set the Advanced Tag value back to 0.

For more information please refer to the Advanced Tag documentation.
