i am new in plc programming . i know the basics difference between the rs232, rs422, rs485. but i am little bit confused in it. so i have the following question regarding these terms.
1. can these protocols communicate with each other i mean rs232 can communicate with rs422 or rs485 and same.
2. my plc has port rs422 but i can connect it with my laptop serial port which is rs232 ?
3. what are the main important points that kept in mind during communication or cross communications.
