By using a programming terminal / pc/laptop with development software. For a control logix family of AB make PLC, install RSlogix5000 software on a laptop and connect to plc on its suitable port, say Ethernet.
You can use the Allen-Bradley counter to standardize your design.
The reason you have to use two switches (a combination of start and stop push button) on PLC is because it is how the program is written.
Meaning of PLC
there r 16th types of plc ok
With a PLC the I/O is fixed when you buy it. Smaller stand alone units are hardwired with the exact I/O you are going to have. Even expandable configurations have a fixed input and output memory table. The PLC scans its Boolean algebra logic, constantly and sequentially, and compares that program to the I/O tables' inputs, outputs and relays. Then it makes its' decisions depending on their state.
Try the Allen Bradley website first?
They all have a unique serial number on them. Allen Bradley can identify where they were manufactured and which distributor or end user actually purchased the PLC. But the unit can only be traced if the person that took it tried to sell it.
Bradley P. Allen has written: 'ART/Ada design project' -- subject(s): Ada (Computer program language)
Programming PLCs is a good field and business to get in. The automation industry is growing at a rapid pace. Many new positions are open for people that can program and troubleshoot a PLC. The largest of the companies that manufacture PLCs are Allen Bradley, Siemens, and Schnieder.
Bradley Allen was born on 1971-09-13.
Not sure which PLC you are looking for, but since you have web access, try www.ab.com and click the literature link. type what you're looking for and most likely you will find it there as they have an excellend website. good luck.

Most Allen Bradley parts are of high quality and durable.

PLC training teaches people how to program a digital computer that controls processes like runing industrial machines. "Much like any other computer system, a programmable logic controller, or PLC, has to be programmed by someone. PLC training is simply the training course that prepares you to program PLCs."
