OpCode

The OpCode drop-down list enables you to specify the type of operation to be performed on the values associated with this function tag.

 For supported calculations that accept multiple values, any Invalid values are ignored (Invalid values include any Function Parameter X fields that have No Tag Selected chosen, have a value of 0, or are left blank).

The operations for supported function tags are:

•    + Function Parameter 1 + Function Parameter 2 + Function Parameter 3 + Function Parameter 4 (excluding any Invalid values).

•    - Function Parameter 1 - Function Parameter 2 - Function Parameter 3 - Function Parameter 4 (excluding any Invalid values).

•    * Function Parameter 1 * Function Parameter 2 * Function Parameter 3 * Function Parameter 4 (excluding any Invalid values).

•    / Function Parameter 1 / Function Parameter 2 / Function Parameter 3 / Function Parameter 4 (excluding any Invalid values).

•    & Function Parameter 1 & Function Parameter 2 & Function Parameter 3 & Function Parameter 4 (excluding any Invalid values).

•    | Function Parameter 1 || Function Parameter 2 || Function Parameter 3 || Function Parameter 4 (excluding any Invalid values).

•    Average Average of Function Parameters 1 through 4 (excluding any Invalid values).

•    Max Maximum of Function Parameters 1 through 4 (excluding any Invalid values).

•    Min Minimum of Function Parameters 1 through 4 (excluding any Invalid values).

•    Integrate Performs time integral of Function Parameter 1 * Function Parameter 2 every Function Parameter 3 seconds.

•    If Function Parameter 2 is not defined, it defaults to a value of 1.

•    If Function Parameter 3 is not defined, it defaults to a value of 1 second. For example, if Function Parameter 2 and Function Parameter 3 were not defined, the calculation would be Function Parameter 1 * 1 every 1 second).

Note: A function tag will return a value of 1 when the specified input tags are invalid and the AND operation is used. Similarly, a function tag will return a value of 0 when the specified input tags are invalid.
