PLC (Programmable Logic Controllers) Networks

 At the end of this lesson, you will have a basic understanding of LAN architecture and topology, communication network access, and transmission media. • Discuss LAN architecture as it applies to industrial networks • Compare the structures of star, common bus, and ring topology, and identify advantages and disadvantages of each configuration • Discuss how error detection is accomplished in the various network topologies • Describe common methods of network access used in PLC systems • Describe different types of transfer medium and identify their pros and cons • Define throughput and describe its impact on system response
