Function blocks allow inputs from the left and pass power through to the right when the function is done or when various conditions are met. Either the timer has timed out or the counter has counted to the preset. Function block usage differs from manufacturer to manufacturer. Function blocks rely on a standard format to enter information

The length of a belt conveyor in metres is the length from the centre of pulley parallel to belt line. Belt length is dependent on both the pulley diameters and centre distances. Capacity is the product of speed and belt cross sectional area. Generally, belt capacity B.C (kg/sec) is given as: B.C =3.6A V ρ Where: A= belt sectional area (m2 ...
