1 What is a typical industrial application for a modular or rack mouted PLC?
2 What is the sequence of operations that occur during programme scanning in a programmable controller?
3 What is the purpose of OPTO - ISOLATION?
I am very new to PLCS. Ive just recieved a 50 question paper. These are just ones i could not find any information on. I would really appreciate any help or pointers to goods websites with general information on PLCS.
Thankyou
