(b) A summons may be issued in any case where a warrant may be issued, and shall be in the same form as the warrant except that it shall summon the defendant to appear before a magistrate at a stated time and place. The summons shall be served upon a defendant by delivering a copy to him personally, or by leaving it at his dwelling house or usual place of abode with some person of suitable age and discretion then residing therein or by mailing it to the defendant's last known address.
