Could someone please explain how to create a one shot timer for the S7-200 in ladder logic? I need to energize an output for 1 sec only after a pushbutton is relased.

Very simple! Use your input to set (latch) a memory bit. Start with this memorybit an on-delay timer (the only kind available with S7-200). Use the output of this timer to reset (unlatch) the memory bit.
