I have just started a plc course and the lecturer is a complete arse who thinks we know everything about plc's without telling us anything. He has set us an assignment to;
describe the design charateristics of typical programmable logic devices
describe different types of input and output devices
describe types of communications links used in plc systems
describe the internal architecture of a typical plc
describe the operation of the cpu.
we have to select a suitable plc type for his system, giving a description of its designand operational charateristics, making reference to its internal architecture.
In addition we must select and describe suitable input and output devices wich will interface the plc to the system specified. We must also describe any communicatio links necessary. HELP....PLEASE!
