MLSyncInitInitializes a synchronizer Pipe Block. Returns TRUE if the function succeeded.
This FB is automatically created in the compiled code of a Pipe Network.
This function block is part of the MLPN_CREATE_OBJECT to initialize the Pipe Network. It is called at the beginning of an application program with the function call:
|
PipeNetwork(MLPN_CREATE_OBJECTS); |

//Initialize a synchronizer Pipe Block named “ SYN” with a modulo of 360, Curve Type of Parabolic, and a distance (DeltaS) of 30 to get in and out of synchronization
MLSyncInit( PipeNetwork.SYN, 360, 1, 30 );
MLSyncReadDeltaSGets the output phasing value of a synchronizer block. Output phasing is the distance or the slope the output takes to synchronize with the input when MLSyncStart Block is executed (see Get Output Phasing after MLSyncStart). It also affects the distance or the slope the output takes to desynchronize with the input and come to a stop when MLSyncStop Block is executed (see Get Output Phasing after MLSyncStop).

MLSyncWriteDeltaSSet the output phasing value of a synchronizer block. Returns TRUE if the function succeeded. Output phasing is the distance or the slope the output takes to synchronize with the input when MLSyncStart Block is executed. It also affects the distance or the slope the output takes to desynchronize with the input and come to a stop when MLSyncStop Block is executed.

When you call the MLSyncStop function, the output value is adapted according to the specified Stop-Position (point B).
The OUTPUT_PHASING parameter is used to define point A, where the flow follows a curve in order to smooth the output value.
When you call the MLSyncStart function, the output value is adapted to catch up with the input value.
The OUTPUT_PHASING parameter is also used to define a curve in order to smooth the output value.
