What is the difference between PLC and PCL?
The order of the letters?
Really, you'll have to give more context.
I found these tables in a datasheet. I do not understand difference between PLC and PCL. I know that PCL shows time when the instrument integrates on the useful signal but i would like other definitions of both of them
Please stop making us guess what you are asking about. What is the instrument? Can you provide a link to the soft copy of the datasheet (like at the manufacturer's website)?
Could be typo?

Separate names with a comma.
