Hi guys
this is my first post, its gonna be great being around here.
I require your help though...
its to be programmed on mel soft gx developer...
question is...

a distribution/counting system consists of product being delivered on two conveyors.

When five product are counted onot static plates at the end of conveyor (1) then this conveyor is stopped and the other conveyor (2) is started.

A pneumatic push mechanism then moves the collation of product on the exit conveyor.

the conveyor (2) is now building a collation, conveyor (1) remains at rest until the collation is complete.

Provide an I/O list for this application and then write a ladder program complete with comments to control this distribution machine. Assume the each conveyor has gaped product being delivered onto it but only when the belt is running.

You need to start the machine at the beginning of a collation and stop the machine at the end of a collation..
