Define the occurrence conditions by combining Script Ver1 and Tag event
If you want to trigger an event under complex conditions that cannot be fully defined using Tag event, you can achieve this by combining it with Script Ver.1 actions.
Specifically, prepare a tag specifically for storing the result of the judgment, judge the condition using script Ver1, and assign the result to the tag for judgment. When the tag is TRUE, Tag event will be generated.
Example) If "U01.F01.T02" is in the range of 50 to 100
U01.F01.T01 = U01.F01.T02 > 50 And U01.F01.T02 < 100 |
Example: If the average value of "U01.F01.T02" and "U01.F01.T03" exceeds 100
U01.F01.T01 = (U01.F01.T02 + U01.F01.T03 ) / 2 > 100 |
In this case, the Script Ver1 action that performs the condition comparison can be called by periodically calculating using the Periodic event or Scheduled event created for that purpose. Alternatively, create Tag event based on the tag used on the right side of the calculation, and set it so that an event occurs when the value of each tag changes, so that Script Ver1 is executed every time the tag used for evaluation changes.

Normally, tags like the above are created using virtual devices or memory devices. Numeric tags for memory devices can also use decimal points. |
