MLPhaInit

Description

Initializes a phaser Pipe Block. Returns TRUE if the function succeeded.

This function block is automatically called by the FunctionA function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. PipeNetwork(MLPN_CREATE_OBJECTS) if a Phaser Block is added to the Pipe Network, with user-defined settings entered in the Pipe Blocks Properties screen.

The Phaser Pipe Block is assigned a Name, OUTPUT_PERIOD, PHASE, PHASE_SLOPE_TYPE, and STANDBY_VALUE.
