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,eError) are present at the outputs for
exactly one cycle.

0 = address 0
1...31 = address 1...31 for standard addressing mode, or
1 A...31 A for extended addressing mode
32 = not used
33...63 = 1 B...31 B for extended addressing mode
newSlaveAddress BYTE New address of Slave
0 = address 0
1...31 = address 1...31 for standard addressing mode, or
1 A...31 A for extended addressing mode
