and Slave Modules. The data exchange is active after reset.

I/O Variables Description
The following table describes the input variables:
Input Type Comment
xExecute BOOL Rising edge: action starts.
Falling edge: resets outputs. If a
falling edge occurs before the
function block has completed its
action, the outputs operate in the
usual manner and are only reset if
either the action is completed or in
the event of an error has been
detected. In this case, the
corresponding output values
(xDone,xError, iError) are
present at the outputs for exactly
one cycle.
xDataExchangeActive BOOL TRUE= enables the data
exchange.
FALSE= disables the data
exchange.
