Hello all new member here. Have upgraded to supporting member status as I will likely be her asking help quite often.
My situation is I just last week was transferred to a electrical maintenance job of a cold reduction steel process mill that is heavily dominated by automation, PLCs and VFD's. While I have a VERY basic understanding of PLC's my last training was a little over 10 years ago. Per my current trainers 95% of my trouble shooting issues will problems control power issues and all either in the PLC's or VFD's but majority PLC problems.
To be absolutely clear I will Not ever need to write or enter PLC programs I will strictly only need to navigate my way through the PLC program to trouble shoot why what ever it is stopped working. My job will be trouble shooting and solving problems 90% are controlled by PLC's.
My current experience electrically speaking has been on traditional industrial electrical power and control systems as it applies to timers, relays, rectifiers to control the speed of three phase motor operation.
I feel I will be best served if I should progress in my training and ask advice based on classifying my self as a PLC novice. Yes I have a basic understanding of PLC's and Ladder logic but thats about it.
The training I will be getting in my new department will be mostly OTJ and instruction by the two most knowledgeable and capable electricians in my department. I will be receiving NO form of organized class room instruction or formal training from my employer to any degree, so that is why I am here.
I am going to supplement my training at work with training and studying on my own time at home.
For my very first three questions I need someone to explain to me in as simple and complete of terms as possible the difference between:
Examine On
Examine Off
I feel there is no point in proceeding with my training in PLC's any farther until I absolutely understand those two terms and the difference between those two terms.
Second question is I need someone to please explain to me the difference between N/O N/C VS Examine on and Examine off.
Once I absolutely understand those two questions I can proceed with my PLC education.
Lastly can someone PLEASE recommend me the best affordable PLC training program for at home learning for a novice wishing to become proficient at trouble shooting PLC's I do not need to be able to program PLC's.
Greatest of thanks as I can not overstate the importance of this to me.
