I/O Wiring PLC standard Symbols

I'm a 5th semester Electrical Engineering Technologist, in Hamilton, ON.
I hoping someone can help me find a list of the standard electrical symbols for an I/O wiring diagram for a PLC project.
I need stuff like limit switches, photos sensors, servos, this kind of hting.
I got most of the basic inputs down, like NOPB and NCPB's, relays and stuff but i need help figuring out how to draw these symbols to document a RS Logix 5 program that i wrote, for School.

Any feedback would be appreciated.

Heres the #1 Google Hit. I kinda had fun with it even after all these years
