Figure 349: Logic diagram for RESIN
Figure 350 describes the principle of the data exchange between all RESIN modules in
the current bay. There is one RESIN function block per "other bay" used in the
reservation mechanism. The output signal EXCH_OUT in the last RESIN functions are
connected to the module bay reserve (QCRSV) that handles the reservation function in
the own bay. The value to the input EXCH_IN on the first RESIN module in the chain
has the integer value 5. This is provided by the use of instance number one of the
function block RESIN, where the input EXCH_IN is set to #5, but is hidden for the user.
