Ok,im relatively new to Ladder logic and ladder diagrams, so im not sure what all these functions, inputs, and outputs are.
What is a Marker (M1, M2, M3, etc..) ?
The help file doesn't help at all either ...

Anybody know?

Hi a marker is an internal memory bit within the PLC. These vary by manufacturer but for Siemens it would be M1.0 for example.

Read any PLC tutorial to learn about this

Alright, do you have a link to a PLC ladder tutorial?
Or is linking to external sites against the rules?

I would suggest you search in Google and/or Youtube the following:

'my plc brand' + tutorial
or
'my plc brand' + getting started
