  • You want to better understand the differences between Profibus DP and Profibus PA and between Profibus and Profinet

  • You need to understand the different methods for connecting field I/O to the controller

  • You need a better understanding of how to wire a Profibus cable to a 9-pin Profibus connector

Description

Modern PLC systems use Remote I/O to connect sensors on the plant floor to PLC controllers located in a different location. This remote I/O strategy eliminates the need for long runs of wiring between each sensor on the plant floor and the PLC, which may be located a hundred feet away.

Using Profibus DP and Profibus PA, the engineer can design a system that uses a single cable to communicate I/O values over a digital bus from I/O cards located near the sensor locations. Interface cards are used at the remote I/O rack to connect the I/O information to the Profibus DP network. Profibus PA can be used to directly obtain data from process sensors and actuators over a separate bus but requires a segment coupler to allow this data to be transmitted to the PLC, which has only Profibus DP ports.

Profinet is another protocol that is popular for communication between PLC hardware and other devices, HMI panels, and Remiote I/O interfaces. Profinet is based on TCP/IP communication and is very different from Profibus DP or PA.

Profibus cables are RS-485 cables with a single pair of single-core wires. Special 9-pin DB shell connectors with terminating resistors are used to connect Profibus DP to a device, such as a PLC. One video of this course will demonstrate how to connect a Profibus cable to the connector, and show how to set the terminating resistor in each connector.

Prepare for better pay & bigger responsibility

Since I started training a few months ago, I can see there’s been a huge difference in how much more efficiently and effectively I can handle PLC repairs in the field. Our clients are telling management how happy they are to get back online more quickly and save money because I’m turning around faster fixes. I definitely recommend it for anyone who needs PLC training at any level.

I needed to get up to speed on working with Siemens PLC equipment and came across RealPars training on YouTube. I watched my first video and immediately went to the website and signed up as a student. I like the way information is explained step-by-step and that it’s broken down into small chunks…I can go back and review anytime I want. I’m already seeing that I can perform repairs faster and with more confidence. Three of my co-workers were so impressed, they signed up for RealPars, too.
