Sequential automation with a siemens S7-300 2

[xJAyx]

I'm programming a pretty simple sequential automation system using a Siemens S7-300 series PLC.
I've programmed a bunch of PLCs in the past but never a siemens and I've never used sequential automation before.
I'm not too worried about the whole thing, but I wanted to just check in to see if anyone has any general tips, sort of benefeit from the collective wisdom so to speak.
Thanks in advance.

The jump distributor is what you want.

The jump number is the state number. Each case is where each state is implemented. Each state has three sections.
The first section get executed the first time the state is entered. The second section gets execute each scan the state is active. The second section check for changes that cause the state machine to go to another state.
The third section get executed when changing from the current state.

There should be one jump distributor or state machine for each task.

You can use SFC's - Sequential Function Charts - try seaching the Siemens web site refered to above for SFC.
