You didn't say what plc, servo, etc. but generally you get a servo control card for your PLC (sometimes called "axis module"), a servo amplifier, and a servo motor.
You place a desired position and some other parameters such as acceleration,deceleration in to registers in the PLC. The PLC card will then output a plus or minus 10 volt signal to the amplifier to move the motor. -10 volts is full speed reverse and +10 volts is full speed forward. +1 volt would be slow forward. An encoder in the motor feeds back its position to the the servo card.
That's only one way. Several companies make stand-alone servo systems (intelligentactuator.com is one) that you either "teach" it a position or command a position and it does the rest.
Depending on what you are doing, you project could be anywhere form easy to maddening.

I can't be of too much help, pulse modulator rings a bell. Also altera makes a programmable logic device board with a servo motor on it. Its called university board or something like that.
