• Processing is executed while Enable is TRUE.
• When Enable changes to TRUE, Busy also changes to TRUE. Enabled is TRUE during calculation of
the output value.
• If an error occurs in the function block, Error changes to TRUE and Busy and Enabled change to
FALSE. When Enable changes to FALSE, Enabled , Busy , and Error change to FALSE.
• If an error occurs, the relevant error code and expansion error code are set in ErrorID (Error Code)
and ErrorIDEx (Expansion Error Code). The error codes are retained even after Error changes to
FALSE, but ErrorID is set to 16#0000 and ErrorIDEx is set to 16#0000 0000 when Enable changes to
TRUE.
• For function blocks that calculate the control amount for motion control, temperature control, etc.,
Enabled is FALSE when the value of CalcRslt (Calculation Result) is incorrect. In such a case, do not
use CalcRslt . In addition, after the function block ends normally or after an error occurs, the value of
CalcRslt is retained until Enable changes to TRUE. The control amount will be calculated based on
the retained CalcRslt value, if it is the same instance of the function block that changed Enable to
TRUE. If it is a different instance of the function block, the control amount will be calculated based on
the initial value.
