New career

I recently started a new job that I have to maybe change some plc programs already written. I havent done it much. I am a journeyman electrician, I did some computerprogramming and I understand the ladder logic, I just havent jumped in it all the way and wondering is it gonna be easy for me to pick up the ball. I have done a lot of trouble shooting to the plc but not much expierince with the program inside. I want to make a good impression at my job and get up to speed an soon as possible. Help?

You didn't say who's hardware you'll be using. Each one is different, although they all accomplish the same thing. You will get a lot more replies to your post by being a little more specific.

Good Luck
